1. INTRODUCTION
1.1 General
This document is valid as of Dragon PTN Release 3.0.
This document describes the 9-L3A-L interface module (=IFM) which provides Layer2 and
Layer3 functionality. This IFM has 9 optical LAN (LAN = Local Area Network) ports on the
front panel: 8*1Gbps SFP ports and 1*10Gbps XFP port. Each individual port can be
configured via HiProvision (=Dragon PTN Management System). 9-L3A-L refers to ‘9 ports –
Layer3 – LAN’.
The 9-L3A-L is a dual slot [n, n+1] IFM which means that it is 2 slots wide. Only the left-hand
side of the IFM in the left-hand slot will be connected to the node backplane.
The 9-L3A-L IFM bandwidth availability on the Dragon PTN backbone depends on the used
node type and the used slots. Depending on the used slot, the IFM can have up to maximum
5 back end ports to the CSM: 1 to 4 (1Gbps) and 1 (10Gbps). The maximum bandwidth
availability is 14 Gbps (=4+10) and can be reached when the IFM is plugged into IFM slots
[S3-S4] of the XT-2209-A node. The available bandwidth per slot overview where the 9-L3A-L
IFM can be used/not used can be found in the table below.

2.1.4 Connectors
This module has following ports:
SFP: 100/1000 Mbps Ethernet optical fiber port / Smart SFP;
XFP: 10 Gigabit Ethernet optical fiber port.
The SFPs/XFPs that can be used for this port can be found in Ref. [7] in Table 2;
2.2 Functional Operation
The 9-L3A-L performs following major tasks:
2.2.1 Media Module for Ethernet: Interfacing to a LAN Network
WAN ports interconnect nodes within the Dragon PTN network (MPLS-TP) whereas LAN
ports interconnect the nodes with their applications. The 9-L3A-L IFM has LAN ports and as a
result can not be used to interconnect nodes. Interconnecting nodes on the WAN side must
be done via LAN/WAN Ethernet IFMs (4-GC-LW, ...).
A LAN port talks Ethernet and a WAN port talks MPLS-TP. As a result, the node can serve as
an edge node (or LER = Label Edge Router) where traffic is received on a LAN port, mapped
into pseudowire and forwarded to the correct label switched path on a WAN port.
For a configured application service, the node can operate as a:
LER = Label Edge Router or access node: The node is located on the edge between the
LAN and WAN. The node converts Ethernet into MPLS-TP and vice versa;
LSR = Label Switching Router: The node is fully located in the WAN. The node has no end-
points for the configured application service, it only forwards MPLS-TP traffic via label
switched paths;
VRF (=Virtural Router forwarding): When an optional Virtual Router has been configured
on the 9-L3A-L IFM, the node operates as a router between different IP subnets.

2.2.2 I/O with the Central Switching Module (=CSM)
The 9-L3A-L module receives Ethernet traffic via its front panel ports and forwards this to the
CSM via the back end ports the CSM. The CSM does all the processing on this data
(synchronization, CRC checks, conversions, switching…). The resulting data will be
forwarded via the backplane to one of the IFMs in the node.
2.2.3 Ethernet Service
a. General
The 9-L3A-L IFM access or end-points communicate over the Dragon PTN network via an
Ethernet service. This service must be configured via HiProvision. This service can operate
port or VLAN based.
b. Port Based / VLAN Based
Port based: Use this mode if all the traffic on a port must be transported transparently in
one and the same service;

VLAN based/VLAN ID: Use this mode if each VLAN (ID) on a port must have its own
service. Ethernet packets with the configured VLAN ID will be forwarded in this service,
other VLAN IDs and untagged packets will be dropped. This behavior can be overruled by
a more advanced VLAN processing in the ‘VLAN Tagging/Untagging’ feature in
HiProvision. This feature also supports VLAN translation which replaces VLAN ID ‘x’ into
VLAN ID ‘y’.
c. VLAN Based Local Service
A VLAN Based Local service is a VLAN based service between only LAN front ports on 9-L3A-L
IFMs. Does not use back end ports, tunnels, WAN ports, the Dragon PTN network and as a
result, this service does not consume network bandwidth.
d. Configuration
See Ref. [1] in Table 2 for more configuration information in HiProvision.
2.2.4 Layer2: VLAN handling
Both port based and VLAN based Ethernet services are supported in which VLANs can be
handled (tagging/untagging behavior, Qos, ...). See Ref. [1] in Table 2 for more configuration
information in HiProvision.
2.2.5 Layer2: QoS (=Quality of Service)
Each Ethernet service can be assigned its own quality of service (bandwidth, priority,
burstsize). See Ref. [1] in Table 2 for more configuration information in HiProvision.
2.2.6 Layer2: MSTP (=Multiple Spanning Tree)
MSTP originally defined in IEEE 802.1s and later merged into IEEE 802.1Q-2003, defines an
extension to RSTP to further develop the usefulness of VLANs. This MSTP instance configures
a separate Spanning Tree for all VLANs included in this instance and blocks all but one of the
possible alternate paths within each Spanning Tree.
If there is only one VLAN in the network, single (traditional) STP works appropriately. If the
network contains more than one VLAN, the logical network configured by single STP would
work, but it is possible to make better use of the alternate paths available by using an
alternate spanning tree for different VLANs or groups of VLANs. More than one VLAN can be
assigned to one MST instance. Multiple MST regions can be operational, each having its own
MSTP instances. The IST (MSTP) instance monitors the entire Region, the CST (MSTP)
instance monitors the links between the regions.
MSTP in a port based service is supported network wide whereas MSTP in a VLAN based
service is supported only locally (not over the 9-L3A-L back end ports). CAUTION: using a
VLAN based service with MSTP over the back end ports could cause loops!
MSTP is fully supported on 9-L3A-L IFMs. On 9-L3A-L IFMs, there is always a default MSTP
running even if no MSTP is configured in HiProvision. See Ref. [1] in Table 2 for more
configuration information in HiProvision.

2.2.7 Layer3: VRF (=Virtual Router Forwarding)
Virtual Router is a router (instance) created by HiProvision within an 9-L3A-L IFM in an
Dragon PTN node. ‘Virtual’ in this context refers to the fact that it is created
programmatically and that multiple routers can be created within the same IFM, with each
Virtual Router having its own independent routing table. Because the Virtual Routers are
independent, the same or overlapping IP addresses can be used without conflicting with
each other. These routing tables initially only have IP addresses/masks of directly connected
networks. Later on, these routing tables will be extended by using Static Routing, OSPF.
Some scalability parameters can be found in §2.2.15. See example figure below. See Ref. [1]
in Table 2 for more configuration information in HiProvision.

2.2.8 Layer3: VRRP (=Virtual Router Redundancy Protocol)
VRRP (=Virtual Router Redundancy Protocol) is a protocol which increases the availability of
the router of a subnet. This redundancy technology is based upon the sharing of a virtual IP
Address amongst all the router interfaces being part of the same VRRP Group. This is
achieved by combining a master and one or more backup router interfaces into one Group.
The actual routing within the Group is done by the master (=active) router interface whereas
the others act as backup. A router interface becomes master after a master election process.
All the router interfaces within a Group use the same unique virtual IP address, e.g
10.10.10.1. The virtual IP address and router interfaces must be in the same subnet. The
virtual IP address will be the default gateway for its associated VLAN e.g. VLAN with VID 150.
The VRRP wizard in HiProvision can create one or more VRRP instances. Each VRRP instance
can be configured between two or more routers. As a result, a Group will always have one or
more backup router interfaces whenever its active router goes down. See Ref. [1] in Table 2
for more configuration information in HiProvision.
Figure 6 VRRP Example
2.2.9 Layer3: Static Routing
The static routing wizard in HiProvision configures or creates static routes (on the virtual
routers) throughout the network. A route is a path from a source towards a destination via
which the message has to travel to reach the destination IP network. There can exist
multiple paths from source to destination, but only one path will be the most efficient one.
Routes (with a same destination) can be favored via a distance parameter. See Ref. [1] in
Table 2 for more configuration information in HiProvision.

Release 01 02/2018
2.2.10 Layer3: OSPF (=Open Shortest Path First)
OSPF is a dynamic routing protocol for IP networks. A dynamic routing protocol always
determines the best possible routing path. For example, determined routes may dynamically
change because a specific route becomes less or more preferred than before.
The concept of OSPF is that routers advertise updates of their link states to neighboring
routers. And the neighboring router does the same to its neighboring router and so on…. In
other words, each router learns from the other routers based on link state advertisements
(=LSA). OSPF is a fast protocol because only updates are advertised.
OSPF checks the availability of others routers in the network by sending ‘Hello’ packets. If
the other router does not respond then that router is assumed to be down. See Ref. [1] in
Table 2 for more configuration information in HiProvision.
Figure 7 OSPF Example
2.2.11 VLAN routing (IPv4) / L3VPN
A L3VPN (or Layer3 VPN) is a routed network within Dragon PTN that interconnects one or
more IP subnets via the MPLS-TP backbone. One or more Ethernet LAN ports from one IP
subnet will be able to communicate with one or more Ethernet LAN ports in another IP
subnet. The L3VPN is created via configuring an MPLS-TP service and one or more local LAN
serivces interconnecting them via a virtual router on a 9-L3A-L IFM. See Figure 3 for a
detailed example. See Ref. [1] in Table 2 for more configuration information in HiProvision.

2.2.12 Storm Control on Ethernet LAN Port
A traffic storm is the growing of excessive network traffic due to Ethernet packets flooding
the LAN. Such a storm can for example occur because of a data loop in the network due to
no or misconfiguration of MSTP. These storms degrade the network performance and must
be avoided whenever possible.
The storm control feature:
is an extra protection against these traffic storms;
can be configured on the IFM ports;
limits the amount of unlearned received data (Unicast, Broadcast, Multicast) on the LAN
port ingress or input side;
limits the amount of transmitted data (all data) on the LAN port egress or output side;
Data that exceeds the configured limitations will be dropped. As a result, a possible data
storm cannot overload the node processor or the node will limit outgoing data.
See Ref. [1] in Table 2 for more configuration information in HiProvision.
2.2.13 Port Mirroring
Port Mirroring is a network debugging or monitoring feature. It is used in the Dragon PTN
node to send a copy of network packets seen on a source port (=mirrored port) to a
destination port (=mirroring port). This feature can be used for network appliances that
require monitoring of network traffic, such as an intrusion-detection system etc... Port
mirroring is supported when source and destination ports are located in the same 9-L3A-L
IFM. See Ref. [1] in Table 2 for more configuration information in HiProvision.
Figure 9 Port Mirroring Example
2.2.14 BPDU Guard via MSTP
BPDU Guard on 9-L3A-L IFMs is supported via the MSTP protocol wizard which can be
configured in HiProvision. BPDU Guard (=Bridge Protocol Data Unit) is a LAN port property or
feature that shuts down the LAN port when a BPDU packet enters this port. As a result, this
feature or IFM:
protects the network against possible loops created via this IFM;
