Requesting suggestions

[nikalleyne]

Morning All,

I have a ticky situation. I have two sites A and C which are connected by MPLS. I have a VPN device in Site A along with other routers. I have two subnet at site B. Subnet 1 and subnet 2. I would like all traffic from subnet 2 go go out the VPN Device in Site A. Is there a way I can reate a route that says "For all traffic COMING from subnet 2 send it to device in site A. I normally create a route specificing the destination and the next hop. However, in this case I would like to specifcy the SOURCE subnet. Or is this something that has to be done through ACL or a route map?

All thoughts welcome.

Hi there,

Policy Based Routing (PBR) may well be your friend in this scenario. I have not used it myself much but it seems like it could give you a solution to this scenario.

There is some info here:

As far as i know you can use an ACL to match the required traffic flow, then apply an action to set the  next hop for the traffic.

Hope this helps,

Jonathan

Will I be able to do this with a Layer 3 switch for which none of the interfaces are performing routing. I have SVIs configured on the switch and this switch is then connected to my MPLS provider network. I take it then my MPLS provider will have to make the configuration on their device. Would that be a correct assumption?
