Frame-Relay multiple subnets mapped to a DLCI

Answered Question
Mar 26th, 2007

Hi experts,

I have a basic question about FR mapping.

Consider the below example config.

interface Serial0

ip address 10.16.1.1 255.255.255.0

frame map ip 10.16.1.2 201 br

frame map ip 172.16.1.1 201 br

encapsulation frame-relay

There are two subnets mapped to a single DLCI 201. Assuming that this is on the central site router, is such a config capable of connecting two spokes to it over the same DLCI ? My idea is that, we would need two DLCIs, one for each spoke.

I feel the FR switch won't know which DLCIs to swap over to take the appropriate VC in order to reach the correct spoke.

Advices please ..

cheers

It is certainly possible to map several subnets to a single DLCI. But a single DLCI connects to a single remote location. So it is not possible to have a single DLCI connect a central site to 2 different remote sites. To connect to 2 different remote sites you would need 2 DLCIs at the central site.

This is exactly what I wanted to clarify.

Thank you
