Question 2

Click on the exhibit below.

A new router named PE-D is to be directly connected to PE-C and is required to be added to the existing VPLS

300. The design requires the least amount of signaling, the least amount of configuration changes for existing

sites and the new site has to have access to all existing sites. How should the new site be added to VPLS 300?

Options :

A : Configure a mesh-sdp between all existing PE routers and the new PE router

B : Configure a mesh-sdp between PE-C and PE-D

C : Configure a spoke-sdp between PE-C and PE-D.

D : It is not possible to meet the design requirements.

Answer: C
