i would like to know how to configure a frame-relay switch so that i can test point-to-multipoint frame-relay? thanks!

i am using a 2500 series with 4 serial interfaces as the switch.

Assume a hub with three pvcs to three remote sites. From the hub side it appears to have a multipoint interface with multiple pvcs. From the spoke side, each pvc is a point-to-point config.

Here is a sample config

frame-relay switching

int s0

frame-relay intf-type dce

frame-relay route 102 int s1 201

frame-relay route 103 int s2 301

frame-relay route 104 int s3 401

int s1

frame-relay intf-type dce

frame-relay route 201 int s0 102

int s2

frame-relay intf-type dce

frame-relay route 301 int s0 103

int s3

frame-relay intf-type dce

frame-relay route 401 int s0 104
