I am setting up an MPLS VPN network.
Customer needs fast convergenace.
So I thought backbone IGP(OSPF) could be configured with fast hellos for the same. At the time of a backbone link failure, even if OSPF converges fast customer is experiencing an outage of 20 seconds between the CPEs(normal ping). I think the longer switchover delay may be due to LDP convergence. Can someone help me with this.
Any idea of reducing LDP convergence time.
I am using 4948 switches.
Thanks in advance
