You are designing an MPLS Layer 3 VPN network where the data path must be the same in both directions. Sites are connected to two PE routers.
Which two design considerations allow this symmetric routing to be achieved? (Choose two.)
A . No equal cost paths for the BGP can be inside the MPLS backbone, and the routing for BGP must use the same path in both directions. The IGP routing does not matter.
B . When Cisco MPLS TE is used, the bidirectional TE tunnel automatically provides symmetric routing.
C . Cisco MPLE TE can be used, but the TE tunnels in both directions must be set up so that the same path is used.
D . No euqal cost paths for the IGP can be inside the MPLS backbone, and the routing for IGP must use the same path in both directions. The BGP routing does not matter.
E . There must not be any equal cost paths for the IGP and the BGP inside the MPLS backbone, and the routing for IGP and the BGP must use the same path in both directions.
Answer: B,E
