Re: Frame-relay switch

Andy,
AFAIK FR switching on Cisco router gives you end-to-end connectivity only,
no multipoint on FR switch side. You have to configure multiple DLCIs per
serial port facing a particular router on FR switch, as the rest of us do.

R1 - 102 - FR switch - 201 R2
R1 - 103 - FR switch - 301 R3
R2 - 203 - FR switch - 302 R3
etc
You are basically to create a mesh topology on FR routers side, not on the
FR switch.
