INE-CCNP ROUTE-IP Routing Overview

Personal notes regarding Frame Relay

Each of the connection need to be manually mapped

R2 static route points to s0/0 will need additional DLCI mapping under the serial0/0 interface. Map each of the routes individually to work. Using the debug command will show the encapsulation failure.

*Mar  1 01:31:26.115: Serial0/0:Encaps failed--no map entry link 7(IP).

Commands

# show frame-relay map - equivalent to show arp
# show frame-relay pvc xxx
# debug frame-relay packet
# debug frame-relay detail
