I am testing Sup720 failover with 7600 IOS 12.2(33)SRD2. I am seeing issues of LDP disconnect and it is causing an outage of approximately 2 minutes. I have enabled BGP and OSPF for NSF. I have also enabled ldp graceful restart. The supervisor switchover is roughly 3 to 4 second but later on during the process of FIB rebuild I am experiencing two minutes outage.
Has anyone successfully configured SSO/NSF with MPLS with failover of 2 -4 seconds?
Would appreciate feedback!!
