(Choose two answers).

ARIPv1, RIPv2, and BGP are distance vector protocols.

BOSPF and IS-IS are distance vector protocols.

CRouting tables are exchanged between neighbors; however, no routing table is transmitted beyond the immediate neighbor.

Routers R1 R2, and R3 are running a classful routing protocol between them. Assuming that router R1 advertises all directly connected networks, how will these networks be represented in router R3's routing table?

ARouter R3's routing table can only contain one of the routes, which will result in route flapping.

BRouter R3's routing table will have one entry for 10.1.1.0/24 and one entry for 10.1.2.0/24.

CThe networks will be represented with one entry of 10.0.0.0/8 in router R3's routing table.

DThe networks will be represented with one entry of 10.0.0.0/24 in router R3's route table.
