Your AS has four BGP routers in a full mesh. Router R1 learns a route from an eBGP peer and advertises it to R2, R3, and R4 via iBGP. R2 also has an iBGP session with R4. When R2 receives the route from R1, which statement is true about R2's behavior toward R4?

R2 advertises the route to R4 only if the next-hop attribute is unchanged.

R2 advertises the route to R4 only if R4 is configured as a route reflector client.

R2 advertises the route to R4 because R2 learned it from an eBGP peer via R1.

R2 does not advertise the route to R4 because iBGP-learned routes are not advertised to other iBGP peers.

Why is a full mesh of iBGP sessions typically required within an AS?

To ensure all iBGP speakers learn all routes

To prevent routing loops between ASes

To allow iBGP routes to be advertised to eBGP peers

To reduce the number of BGP sessions

You are configuring iBGP between two routers in the same AS. The routers are not directly connected; they are separated by two hops. What must you configure for the iBGP session to establish?

The routers must use their loopback addresses for the BGP session.

The routers must be configured with a route reflector.

The routers must be directly connected with a point-to-point link.

The routers must have different AS numbers configured.

Your AS has five BGP routers. You want to ensure that all routers receive all BGP routes without configuring a full mesh. Which solution should you implement?

Configure a route reflector on one router and make the other four routers clients.

Configure all routers with the same AS number and establish eBGP sessions between them.

Configure BGP confederations to divide the AS into sub-ASes.

Configure a full mesh of iBGP sessions between all five routers.
