2 Ethernet Interfaces and 2 PVC's on an 1841

Answered Question
Jul 15th, 2008

What is the proper routing configuration when you have a router with two FastEthernet interfaces connected to two different networks and you want to route them out of two different PVC's? We are currently using static routing and only have one default route configured.


I would think all traffic is being routed over one PVC.


example:


interface Serial0/0/0.1 point-to-point

description *** Frame Relay PVC 1 ***

ip address 10.200.250.98 255.255.255.252

frame-relay interface-dlci 524 IETF

!

interface Serial0/0/0.2 point-to-point

description *** Frame Relay PVC 2 ***

ip address 10.200.254.58 255.255.255.252

frame-relay interface-dlci 500 IETF

!

ip route 0.0.0.0 0.0.0.0 10.200.254.57

!


Would you use PBR to define which sub-interface to route out or is there another way?

You'll have to create a route-map permiting the networks you want for each interface. So basically a permit / deny and then set your next hop gateway.

Based on what you have shown us so far and what you have described, I would say that yes PBR is the solution to have traffic from one FastEthernet go out 1 frame relay subinterface and traffic from the other FastEthernet go out the other frame relay subinterface.


And yes what you have posted would result in all traffic being routed out a single subinterface.
