Not sure if this is related to MPLS but I am trying to find some information on how to simulate multiple routers on one physical box. It has something to do with Vrf's I think but cannot be certain. Thank you
Using VRF's you can create virtual routing-tables within your router that are specific to that VRF. Routes within a VRF are not visible from within the global routing table or other VRF's unless you explicitly choose to import/export them.
You can run VRF specific instances of routing protocols also if you need to involve more than 1 router.
Generaly MPLS is used between several routers, however it is possible to configure a router with some simple MPLS configuration to split a single router into several VRF's (VPN routing and forwarding). The configuration would be something like :
ip vrf customer_a
route-target export 1:1
route-target import 1:1
ip vrf customer_b
route-target export 2:2
route-target import 2:2
You apply these VRF's to an interface by :
ip vrf forwarding customer_a
A couple of things to keep in mind are that when you apply the "ip vrf forwarding xxxxx " command to an interface it will remove and existing ip addresses from that interface. Also I have hound that OSPF does stange things sometimes on routes learnt from an interface that is in a VRF. Experiment with the OSPF router command "capability vrf-lite"
