The OSPF packets shown have been exchanged between two neighbors. What state is the OSPF adjacency in?

A.

The adjacency state is two way because both routers have received a database description packet.

B.

Use a prefix list on router R1 to discard all ingress IS-IS routes.

C.

Use an export policy and prefix list on router R1 to reject this route.

D.

This is not possible because RIP cannot use import policies.

When a router receives an IP packet, but does not find a match in the routing table for the destination IP address, what actions are performed by the router?

The packet is flooded out all router interfaces.

B.

The packet is dropped and an ICMP unreachable message is sent back to the source.

C.

The packet is silently discarded.

D.

The packet is flooded out all interfaces and an ICMP unreachable message is sent.
