About This Guide
This guide describes logical IP routing interfaces, IP and MAC-based filtering support provided by
the 7210 SAS D, E, K OS and presents configuration and implementation examples.
On 7210 SAS devices, not all the CLI commands are supported on all the platforms and in all the
modes. In many cases, the CLI commands are mentioned explicitly in this document. In other
cases, it is implied and easy to know the CLIs that are not supported on a particular platform.
NOTE: 7210 SAS-E and 7210 SAS-D operate in access-uplink mode by default. No explicit user
configuration is needed for this.

Configuring IP Router Parameters
Configuring IP Router Parameters
In order to provision services on a 7210 SAS device, logical IP routing interfaces must be
configured to associate attributes such as an IP address or the system with the IP interface.
A special type of IP interface is the system interface. A system interface must have an IP address
with a 32-bit subnet mask.
The following router features can be configured:
• Interfaces on page 16
Interfaces
7210 SAS routers use different types of interfaces for various functions. Interfaces must be
configured with parameters such as the interface type (system) and address. A port is not
associated with a system interface. An interface can be associated with the system (loopback
address).
System Interface
The system interface is associated with the network entity (such as a specific router or switch), not
a specific interface. The system interface is also referred to as the loopback address.
The system interface is used to preserve connectivity (when routing reconvergence is possible)
when an interface fails or is removed. The system interface is also referred to as the loopback
address and is used as the router identifier.

The TiMOS implements IP routing functionality, providing support for IP version 4 (IPv4) and IP
version 6 (IPv6). IP version 6 (RFC 1883, Internet Protocol, Version 6 (IPv6)) is a newer version
of the Internet Protocol designed as a successor to IP version 4 (IPv4) (RFC-791, Internet
Protocol). The changes from IPv4 to IPv6 effects the following categories:
• Expanded addressing capabilities — IPv6 increases the IP address size from 32 bits (IPv4)
to 128 bits, to support more levels of addressing hierarchy, a much greater number of
addressable nodes, and simpler auto-configuration of addresses. The scalability of
multicast routing is improved by adding a scope field to multicast addresses. Also, a new
type of address called an anycast address is defined that is used to send a packet to any one
of a group of nodes.
• Header format simplification — Some IPv4 header fields have been dropped or made
optional to reduce the common-case processing cost of packet handling and to limit the
bandwidth cost of the IPv6 header.
• Improved support for extensions and options — Changes in the way IP header options are
encoded allows for more efficient forwarding, less stringent limits on the length of
options, and greater flexibility for introducing new options in the future.
IP Router Configuration
• Flow labeling capability — The capability to enable the labeling of packets belonging to
particular traffic flows for which the sender requests special handling, such as non-default
quality of service or “real-time” service was added in IPv6.
• Authentication and privacy capabilities — Extensions to support authentication, data
integrity, and (optional) data confidentiality are specified for IPv6.

Figure 1: IPv6 Header Format
Table 2: IPv6 Header Field Descriptions
Field Description
Version 4-bit Internet Protocol version number = 6.
Prio. 4-bit priority value.
Flow Label 24-bit flow label.
Payload Length 6-bit unsigned integer. The length of payload, for example, the rest of the
packet following the IPv6 header, in octets. If the value is zero, the payload
length iscarried in a jumbo payload hop-by-hop option.
Next Header 8-bit selector. Identifies the type of header immediately following the IPv6
header.
This field uses the same values as the IPv4 protocol field.
Hop Limit 8-bit unsigned integer. Decremented by 1 by each node that forwards the
packet.
The packet is discarded if the hop limit is decremented to zero.
Source Addres 128-bit address of the originator of the packet.
Destination Address 128-bit address of the intended recipient of the packet (possibly not the ulti-
mate recipient if a routing header is present).

IPv6 Applications for 7210 SAS-D
The IPv6 applications for 7210 SAS-D are:
• IPv6 inband management of the node using access-uplink port IPv6 IP interface
• IPv6 transit management traffic (using access-uplink port port IPv6 IP interfaces)
DNS
The DNS client is extended to use IPv6 as transport and to handle the IPv6 address in the DNS
AAAA resource record from an IPv4 or IPv6 DNS server. An assigned name can be used instead
of an IPv6 address as IPv6 addresses are more difficult to remember than IPv4 addresses.

Process Overview
Process Overview
The following items are components to configure basic router parameters.
• System interface — This creates an association between the logical IP interface and the
system (loopback) address. The system interface address is the circuitless address
(loopback)
Page 20 7210 SAS D, E, K OS Router Configuration Guide
Configuration Notes
The following information describes router configuration guidelines.
• A system interface and associated IP address should be specified.
• Boot options file (BOF) parameters must be configured prior to configuring router
parameters.
• IPv4 and IPv6 route table lookup entries are shared. Before adding routes for IPv6
destinations, route entries in the routed lookup table needs to be allocated for IPv6
addresses. This can be done using the CLI command config> system> resource-profile>
max-ipv6-routes. This command allocates route entries for /64 IPv6 prefix route lookups.
The system does not allocate any IPv6 route entries by default and user needs to allocate
some resources before using IPv6. For the command to take effect the node must be
rebooted after making the change. Please see the example below and the Systems Basic
guide for more information.
• A separate route table (or a block in the route table) is used for IPv6 /128-bit prefix route
lookup. A limited amount of IPv6 /128 prefixes route lookup entries is supported. The
software enables lookups in this table by default (in other words no user configuration is
required to enable IPv6 /128-bit route lookup).
IP Router Configuration
• IPv6 interfaces are allowed to be created without allocating IPv6 route entries. With this
only IPv6 hosts on the same subnet will be reachable.

Router Configuration Overview
Router Configuration Overview
In a 7210 SAS, an interface is a logical named entity. An interface is created by specifying an
interface name under the
context where objects like static routes are defined. An IP interface name can be up to 32
alphanumeric characters long, must start with a letter, and is case-sensitive; for example, the
interface name “1.1.1.1” is not allowed, but “int-1.1.1.1” is allowed.
To create an interface on an Alcatel-Lucent 7210 SAS router, the basic configuration tasks that
must be performed are:
• Assign a name to the interface.
• Associate an IP address with the interface.
• Associate the interface with a system or a loopback interface.
A system interface should be configured.
configure>router context. This is the global router configuration
System Interface
The system interface is associated with the network entity , not a specific interface.
The system interface is used to preserve connectivity (when routing reconvergence is possible)
when an interface fails or is removed. The system interface is used as the router identifier. A
system interface must have an IP address with a 32-bit subnet mask.

Common Configuration Tasks
Common Configuration Tasks
The following sections describe basic system tasks.
• Configuring a System Name on page 26
• Configuring Interfaces on page 27
→ Configuring a System Interface on page 27
Configuring a System Name
Use the system command to configure a name for the device. The name is used in the prompt
string. Only one system name can be configured. If multiple system names are configured, the last
one configured will overwrite the previous entry.
If special characters are included in the system name string, such as spaces, #, or ?, the entire string
must be enclosed in double quotes. Use the following CLI syntax to configure the system name:
CLI Syntax: config# system
name system-name
Example
: config# system
config>system# name ALA-A
ALA-A>config>system# exit all
ALA-A#
The following example displays the system name output.
A:ALA-A>config>system# info
#-----------------------------------------# System Configuration
#----------------------------------------- name "ALA-A"
location "Mt.View, CA, NE corner of FERG 1 Building"
coordinates "37.390, -122.05500 degrees lat."

Configuring Interfaces
The following command sequences create a system IP interface. The system interface assigns an
IP address to the interface in the IES context and create logical IP interfaces for inband
management.
Note that the system interface cannot be deleted.
Configuring a System Interface
To configure a system interface:
CLI Syntax: config>router
interface interface-name
address {[ip-address/mask]|[ip-address] [netmask]}
