You are designing a Group Encrypted Transport virtual 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
