Area Border Router?

[flex001 10]

Hi,

 

According to the exhibit what are the roles of R2?

 

1. Backbone Router

2. Interior Router

3. Area Border Router

4. Autonomous System Boundary Router

 

Correct answer(s): 1 4

 

Explanation: Backbone Routers are routers that have at least one interface connected to the Backbone. Interior Routers are routers whose interfaces are all in the same area. Area Border Routers are routers that connect one or more area to the Backbone. Autonomous System Boundary Routers are routers that “inject” routes learned from another routing protocol (BGP, EIGRP, RIP,…) into the OSPF domain.

also meiner Meinung nach ist dann doch Antwort 3 auch richtig, oder?
