Question #: 19
Topic #: 4

Based upon the exhibit, which of the following statements is FALSE?

AVPLS 10 must be configured with two BGP instances on PE3 and PE4.

BOn PE3 and PE4, VPLS 10 must be configured with two different route-distinguisher values: one for VXLAN and another for MPLS.

COn PE3 and PE4, VPLS 10 must be configured with two different route-target values: one for VXLAN and another for MPLS.

DA BGP export policy is required on PE3 and PE4 to ensure that IMET routes originated with VXLAN encapsulation are not advertised to the peer across the core network.

Show Suggested Answer

Suggested Answer: C

PE2 advertises a MAC/IP route for MAC1 with a sequence number higher than that received from PE1. This indicates that MAC1 has moved from PE1 to PE2 and triggers a MAC withdrawal message from PE1 to remote PEs.CE1 does not generate an update message to PE1 withdrawing its MAC, nor does PE1 generate an update message to remote PEs identifying the new location of CE11.

C) seems false to me. The network identifier is 100, not 10.

I'm leaning towards B) since the exhibit shows the neighbors have proxy-ARP enabled. Tricky question!

Yes, I agree. The exhibit clearly indicates that neighbors 10.10.10.2 and 10.10.10.3 have proxy-ARP enabled for the VPLS.
