Routing

Hi,

I got confused on the function of "P2MP". What's it's real purpose ?

Regarding to my backbone, I don't see any information what is relevant about P2MP.

My network just need LDP Label with RSVP backup-LSP. 

Or something need it to share routes. Like BGP L3 VPN or L2circuit ?

> show ldp p2mp tunnel

{master}

> show ldp database p2mp

If You followed this example https://www.juniper.net/documentation/en_US/junos/topics/topic-map/ldp-configuration.html#id-configuring-ldp-link-protection and enabled P2MP LDP, then this is expected.

Do You have a line in Your config that reads "set protocols ldp p2mp"?

Thx

Hi Alex,

As your URL, I think we need it since we enable basic LFA+Dynamic RSVP LSP.

So, my configuration is included this link.

Best regards,
