mpls ldp neighbor targeted
MP-250
Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
The mpls ldp neighbor targeted command can improve label convergence time for directly connected
neighbor LSRs when the links directly connecting them are down. When the links between the neighbor
LSRs are up, both the link and targeted Hellos maintain the LDP session. If the links between the
neighbor LSRs go down, the targeted Hellos maintain the session, allowing the LSRs to retain labels
learned from each other. When a link directly connecting the LSRs comes back up, the LSRs can
immediately reinstall labels for forwarding use without having to reestablish their LDP session and
exchange labels.
Examples In the following example, the router sets up a targeted session with the neighbor 10.10.10.10 using TDP
as the label protocol:
Router(config)# mpls ldp neighbor 10.10.10.10 targeted
In the following example, the router sets up a targeted session with the neighbor 10.10.10.10 using LDP
as the label protocol:
Router(config)# mpls label protocol ldp
Router(config)# mpls ldp neighbor 10.10.10.10 targeted
Another way to set up a targeted session using LDP without changing the default label protocol is as
follows:
Router(config)# mpls ldp neighbor 10.10.10.10 targeted ldp
