Question 251
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?
