I came across a nice post on Traffic Protection on MPLS (RSVP)
I have one question about the diagram in that post.
There is an LSP r1-r7 (r1-r3-r6-r5-r7)
Part 2. Link Protection
The example configured link-protection to protect the link between r5 and r7.
My question is whether I should configure all the rsvp -enabled interfaces with link-protection on all the transit routers from ingress to egress routers, or only on the interfaces facing each other between r5 and r7.
I like to know which interfaces are exactly enabled with link-protection.
From my lab, it seems only the interface fe-0/0/1 on R5 facing R7 needs to have link-protection enabled.
Like to get some confirmation from more experienced people here.
thanks a lot in advance !!
