Question 295

Which of the following statements regarding MPLS BGP VPN is false?

PEs and CEs can exchange routing information using static routes, OSPF multi-instance, IS-IS multi-instance, and EBGP.

BGP SoO is used to prevent the routes advertised from a VPN site from returning to the site after traversing the MPLS backbone network. SoO is an extended community attribute automatically generated by MP-BGP.

Typically, PEs at both ends of an IBGP session establish, a stable BGP peer relationship using the loopback interface address.

The TTL field in the label is used to prevent loops.

Which of the following statements are true?

(Choose all that apply.)

R5 can learn the route to the loopback interface of R2.

R3 can learn the route to the loopback interface of R2.
