Configuing MPLS LDP session protection on specific interfaces only.

[Venison Mogambi]

I was reading about MPLS LDP session protection. As I understand it's configured in Global config for the entire router, e.g.:

Router(config)#mpls ldp session protection

It seems like you would want the option to enable this only on certain interfaces. Is there a way to enable it on a single interface, or a way to disable it on some interfaces after you've enabled it globally?

Hi,

you can use "mpls ldp session protection [vrf vpn-name] [for acl]" for specify the LDP peers that should be protected.

The access list (acl) you can configure lets you specify the LDP peers that should be protected. It should hold the LDP Router Identifier  of the LDP neighbors  that need protection.

here is example:

R1

access-list 1 permit 2.2.2.2

mpls ldp session protection for 1

mpls ldp discovery targeted-hello accept

R2

access-list 1 permit 1.1.1.1

mpls ldp session protection for 1

mpls ldp discovery targeted-hello accept
