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?

  1. The packet is flooded out all router interfaces.
  2. The packet is dropped and an ICMP unreachable message is sent back to the source.
  3. The packet is silently discarded.
  4. The packet is flooded out all interfaces and an ICMP unreachable message is sent.

Answer(s): B



In IS-IS database synchronization, each router compares each LSP described in the received CSNPs with the LSPs in its own database. Which of the following actions is taken if the database contains a newer copy of the LSP?

  1. The router sends a copy of the LSP from its database to its neighbor
  2. The router sends a PSNP to its neighbor describing the LSP in its database.
  3. The router updates its database with the LSP and floods a copy to its other neigbors.
  4. The router sends a PSNP to its neighbor to request the LSP.

Answer(s): A
