Hi, everyone.

I'm going to deploy MPLS for MPLS VPN services.

we'll make LSP topology in my IP network according to the shortest path of IGP.

I'm wondering what happen if the LSP fails due to link failure or node failure, etc.

Could explain about process to make a new LSP instead of the failed LSP within the failed link ?

(Let's assume Cisco only network.)

 

As you know, a LSP between PEs has the deep relationships with customer's inner LSP.

I think LSP failure is criticla in MPLS VPN services.

If link fail, IGP routing table will be updated.  and then A new LSP between PEs will be generated according to updated routing information.

is it right ? then how long does it take to make a new LSP ?

is there any LSP failure except link/node failure ?

 

thanks
