• New transport class-based architecture to facilitate service mapping over colored tunnels (ACX Series, PTX Series, MX Series)—S r n in Junos OS Release 21.1R1, you can classify colored transport tunnels (RSVP, IS-IS fl x b algorithm) in your network into transport classes and map service routes over an intended transport class. You can also extend the transport tunnels to span across m domains (ASs or IGP areas) by using the new BGP transport address family called BGP Classful Transport (BGP CT).

Junos OS Release 21.1R1, Junos fusion for provider edge supports Interprovider and Carrier-of- |

recursive VPN) model where one carrier (VPN service customer) transports its VPN |
r |
c inside |

another carrier’s VPN (VPN service provider). Junos fusion for provider edge currently supports |

support for PE routers for VPN service providers along with VPN service customers. |

Juniper Networks IDP supports Snort IPS signatures. IDP secures your network by using signatures |
||||||
that help to detect |
c s Snort is an open-source intrusion r v |
n |
n system (IPS). You can |

convert the Snort IPS rules into Juniper IDP custom |

Snort Tool (JIST). These rules help detect malicious |

|
|
|
• JIST is included in Junos OS by default. The tool supports Snort version 2 and version 3 rules.
• JIST converts the Snort rules with snort-ids into equivalent custom |
c signatures on Junos OS |
|
with r s c v snort-ids as the custom |
c names. |
|
•When you run the request command with Snort IPS rules, JIST generates set commands equivalent to the Snort IPS rules. Use the request security idp jist-conversion command to generate the set commands as CLI output. To load the set commands, use the load set terminal
|
statement or copy and paste the commands in the c n r |
n mode, and then commit. You can |
|||
|
then c |
n r the x s |
n IDP policy with the converted custom |
c signatures. |
|
• |
All the Snort IPS rule |
s that didn’t get converted are wr |
n to /tmp/jist-failed.rules. The error |
||
|
log |
s generated during the conversion are wr n to /tmp/jist-error.log. |

To view the jist-package version, use the show security idp jist-package-version command. |

Support for unicast ARP request on table entry x r n—You can c n r |
the device to send a |
|
unicast ARP request instead of the default broadcast request when an ARP table entry is about to |
||
expire. The retry requests are unicast at intervals of 5 seconds. Without this |
n the retry requests |
are broadcast at intervals of 800 milliseconds. This behavior reduces ARP overall broadcast r c It also supports the use case where access nodes are c n r not to forward broadcast ARP requests toward customer CPEs for security reasons and to instead translate ARP broadcasts to unicast requests.
To c n rm whether this is c n r you can issue the following command: show c n r |

arp | grep unicast-mode-on-expire. |
