CISCO Router Question

By joshg ·
Can you have multiple unique DLCI entries on the same subinterface? The routers are 3600's and 2600's running IOS 12.0 and 11.3. The serial interface on the 3600 is a T1 connected to six other fractional T1's connected to the 2600's. How would youget each circuit to work on the same interface that way I don't have to have six different sub interfaces with different IP's. I thought of adding the DLCI's of the 6 other circuits to the same subinterface.

No problems - You need to create point-to multipoint subinterface :
int s0.1 point-to-multipoint
frame-relay interface dlci 30
frame-relay interface dlci 31
frame-relay interface dlci 35
etc...

Thank you but can you change the interface from point-to-point to multipoint, or do I have to create a new subint? I have tried but the router tells me I cannot change the link type. Send me an e-mail

Absolutely. Go into config for the interface and issue the frame map XXXXX DLCI XX. Add as many as you have configured.
