We have a network running MPLS TE tunnels in the core. Cisco CRS-1 (IOS XR 3.5.3) in the core layer and 7609S (IOS 12.2(33)SRB2) at distribution layer. MPLS TE tunnels form full mesh from any 7609S to any other 7609S. It is in production.
Due to systematic naming change, I need to update tunnel names signalled via RSVP. During test, I observed after I updated tunnel name at tunnel headend, by changing tunnel description, local tunnel name changed, but corresponding mid and tail end tunnel name remain to be old one. My question is, is there a way to signal tunnel name via RSVP manually, without having to bring LSP hard down?
