Posts here will mostly contain full configuration files for my own reference and will not likely not have much explanation. See posts in the Guides category for more explanational posts.
This is the procedure for configuring a frame relay switch. This requires lots of serial interfaces.
We need to go through the procedure of enabling frame-relay switching before anything can be configured. The initial configuration is extremely complex. Please study the next setting of commands carefully!
R1# frame-relay switching
Whew! That was complicated. Feel free to go back and review if necessary. Otherwise, it’s time to configure the serial interfaces.
Follow this example configuration. Basically we are entering static routes that connect one interface to another. The DLCIs need to be provided to the connecting routers.
The below configuration is below the router performing the frame-relay functions. Just for this example, we require three serial ports.
interface Serial0/0 no ip address encapsulation frame-relay clock rate 8000000 frame-relay intf-type dce frame-relay route 102 interface Serial0/1 201 frame-relay route 103 interface Serial0/2 301 ! interface Serial0/1 no ip address encapsulation frame-relay clock rate 8000000 frame-relay intf-type dce frame-relay route 201 interface Serial0/0 102 ! interface Serial0/2 no ip address encapsulation frame-relay clock rate 8000000 frame-relay intf-type dce frame-relay route 301 interface Serial0/0 103
Configuring Connected Routers
Virtual interfaces & the wheel spoke thingy is recommended.
The below configuration is something that would be configure on the routers connecting to the one functioning as the frame relay switch.
interface Serial0/0 no ip address encapsulation frame-relay ! interface Serial0/0.102 point-to-point ip address 10.1.0.1 255.255.255.252 frame-relay interface-dlci 102 !
