BGP (Border Gateway Protocol) is a routing protocol that is used to exchange routing information between different networks on the internet. It is widely used by internet service providers (ISPs) and large enterprises to connect their networks to the internet.
The three true statements about BGP are:
A. iBGP peering adds value in small networks with a single upstream connection: In a small network with a single upstream connection, iBGP peering can add value by allowing all routers within the network to exchange routing information. This ensures that all routers in the network have the same view of the network topology, and any changes in the network can be quickly propagated to all routers.
B. iBGP peering adds value in small networks with multiple upstream connections: In a small network with multiple upstream connections, iBGP peering can add value by allowing all routers within the network to exchange routing information. This ensures that all routers in the network have the same view of the network topology, and any changes in the network can be quickly propagated to all routers.
C. eBGP peering adds value in small networks with multiple upstream connections: In a small network with multiple upstream connections, eBGP peering can add value by allowing the network to receive multiple routes from different ISPs. This enables the network to choose the best path for outbound traffic based on factors such as path length, cost, and quality of service.
D. iBGP peering adds value in large enterprise environments with multiple upstream connections: In a large enterprise environment with multiple upstream connections, iBGP peering can add value by allowing all routers within the enterprise to exchange routing information. This ensures that all routers in the enterprise have the same view of the network topology, and any changes in the network can be quickly propagated to all routers.
E. eBGP peering adds value in large enterprise environments with multiple upstream connections: In a large enterprise environment with multiple upstream connections, eBGP peering can add value by allowing the enterprise to receive multiple routes from different ISPs. This enables the enterprise to choose the best path for outbound traffic based on factors such as path length, cost, and quality of service.
In summary, BGP is an important protocol for connecting networks to the internet. iBGP and eBGP peering can add value in different network scenarios, depending on the size of the network and the number of upstream connections. iBGP is useful for exchanging routing information within a network, while eBGP is useful for receiving multiple routes from different ISPs.
