Configuring Static SRLG Value to Topology Link

Perform this task to assign static SRLG value to a topology link based on its IP address. Use this command
for platforms that do not support SRLG flooding, so that the local node auto-tunnel backup diverse path
calculation is based on static SRLG.
SUMMARY STEPS
1. configure
2. mpls traffic-eng srlg
3. value srlg-value
4. static ipv4 address ip-address next-hop ipv4 address next-hop-ip-address
5. Use the commit or end command.

Purpose
Enters global configuration mode.
Enters MPLS TE SRLG configuration mode.
Enters MPLS TE SRLG value configuration mode and configures
SRLG value. The example shows how to enter MPLS TE SRLG
value configuration mode and configure a SRLG value of 5.
Configures static SRLG value to a topology link. The example
shows how to configure static SRLG value for a topology link with
source IP address of 1.1.1.1 and next-hop IP address of 1.1.1.2.
commit—Saves the configuration changes and remains within the
configuration session.
end—Prompts user to take one of these actions:
• Yes— Saves configuration changes and exits the configuration
session.
• No—Exits the configuration session without committing the
configuration changes.
