Youare designing a Group Encrypted Transportvirtual private network solution for an existing
branch network. The existing network has the following characteristics:
 50 remote sites (with an additional 30 remote sites expected over
the next 3 years)
 Connectivity between all sites is via Multiprotocol Label Switching
Layer 3 virtual private network service from a single provider
 Open Shortest Path First is the routing protocol used between
provider edge and customer edge routers
 The customer edge routers will become group members
performing the encryption between sites
Which additional routing protocol would you use for the overlay routing between the group
members?

A.
Open Shortest Path First (with a different process ID)

B.
Enhanced Interior Gateway Routing Protocol

C.
No additional protocol is necessary.

D.
External Border Gateway Protocol

E.
Routing Information Protocol Version 2

F.
Next Hop Resolution Protocol
