• B.True

• A.Only routes learned from IBGP.
• B.All BGP routes learned from all neighbors.
• C.Only learned routes from EBGP.
• D.Only the best route that is preferred by BGP.

The following configuration commands for issuing default routes for each protocol, which is wrong?

• A.In the BGP protocol, the default-route imported command is used to enable the default route to be imported into the BGP routing table.
• B.In the RIP protocol, the default route originate command is used to generate a default route on the current router or send the default route in the routing table to the neighbor.

What are the advantages of IS-IS compared to OSPF? (Multiple Choice)

• A.IS-IS message structure is simple
• B.Excellent routing algorithm
• C.More extensibility
• D.Stronger routing capacity

• A.network cannot be used with the corresponding policy.
• B.The route injected through the network must exist in the IP routing table.
• C.The injected route needs to strictly match the mask length in the IP routing table.
