Refer to the exhibit. Router R1 is seeing routes that are advertised by router R2, and R2 is seeing routes that are advertised by R1. OSPF is being used by the company that owns and controls routers R1 and R2. Which two situations are evident with this L3 MPLS VPN topology? (Choose two.)
- Router R1 has an established OSPF neighbor relationship with R2.
- Any other P routers within the cloud that are part of the MPLS domain between R1 and R2 use BGP as a routing protocol.
- Router R1 has an established OSPF neighbor relationship with PE1.
- Routers R1 and R2 redistribute routes into MP-BGP.
- The PE routers use MP-IBGP to exchange the routes between R1 and R2.
Explanation: R1 and PE1 exchange routes using OSPF. The same is true for R2 and PE2. Each PE router (that is under the control of the provider) redistributes routes into MP-BGP to be exchanged with the other PE router. Once a route is received, the PE router redistributes the route into OSPF and places it in a customer-specific VRF instance so that the route can be exchanged with the customer-controlled router.
