Muliple Frame PVC's on a 1751

[rjcoderre]

Can a T'1 interface on a 1751 be configured with more than one Frame Relay PVC? Does it use sub interfaces? What is the max number of Ethernet interfaces availabe on the 1751?

Yes, you will configure subinterfaces and configure them using the remote DLCI number.

If you have a T1 running Frame Relay it can have a single or can have multiple PVCs (it depends on what you have contracted with the provider). If there are two or more PVCs then you have choices about how to configure them. It is generally accepted as the best solution to configure each PVC on a separate point to point subinterface and is most often done this way. But there are other choices: you can assign all of the PVCs to the physical interface with no subinterfaces (this is a multi-point solution). Or you can have some PVCs on the physical interface and some on subinterfaces. Or you can have some of the PVCs on multi-point subinterfaces.

So there are lots of choices. The decision about which would be best would depend on the situation in your network.

from global:

show frame pvc

[will list the advertised DLCIs]

conf t

int s0

no ip address

encap frame-relay ietf

exit

int s0.1 point-to-point

ip address 172.16.1.1 255.255.255.252 [your ip here]

frame-relay interface-dlci 300 [your dlci here]

exit

exit

And of course configure the other side the same way.

Let me know if this helps!
