Verifying Rendezvous Points

Even when PIM routing is in place, RPs must be configured correctly to find traffic sources. The command show ip pim rp allows you to inspect the configured RPs and look at the mappings that have been applied. The full command is  Router(config)#show ip pim rp [group-name | group-address | mapping]   Using show ip pim rp, without further modifiers, displays RPs for active groups. If the command is modified with the group name, then only the RPs for the select..

LDP/TDP Session Establishment

When you start MPLS on the first interface in a router, the TDP/LDP process is started and the Label Information Base (LIB) structure is created. The router also tries to discover other LSRs on the interfaces running MPLS through TDP hello packets. The TDP hello packets are sent as broadcast or multicast UDP packets, making LSR neighbor discovery automatic. The debug tag tdp transport command can monitor the TDP hellos. Example C-4 shows the TDP process startup and Example C-..

RFC 1973 and Cisco Implementation of PPP over Frame Relay

RFC 1661 defines the standard PPP specifications, whereas a separate RFC document, RFC 1973, describes a standard method for transporting PPP over a Frame Relay VC connection. Cisco's implementation of the PPP over Frame Relay feature is based on the RFC 1973 specifications. A Cisco router supporting the PPP over Frame Relay feature is able to establish an end-to-end PPP session over an active Frame Relay PVC.   NOTE Note that Cisco's implementation of RFC 1973 to suppor..
