Use an import policy and a prefix list on router R2.

Use an export policy and a prefix list on router R1.

Use an import policy and a prefix list on router R1.

Router R1 cannot discard the route because IS-IS does not support import policies.

Router R2 needs a static route to the PC.

Router R2 needs a default to router R1.

Router R1 needs a default route to router R2.

The static route should use a next-hop of 172.31.1.2

To give IPv6 traffic preferential routing over IPv4 routes.

To allow core routers running only IPv6 protocols to carry IPv4 traffic.

To give IPv4 only routers the ability to route based on IPv6 addresses.

To allow IPv6 traffic to pass through an IPv4 network.

The convergence time depends on the value of the OSPF hello timers on routers R1 andR3.

The convergence time depends on the value of the OSPF hello timers and Dead interval on routers R1 and R3.

The convergence time depends on the value of the BFD interval and multiplier settings on routers R1 andR3.

The convergence time depends on the time taken by the switches to detect the link failure.

The link-state information is not populated in the database, but is forwarded to all neighbors.

The link-state information already in the database is overwritten and the age is reset.

The link-state information is not populated in the database and an acknowledgement is sent.

The link-state information is regarded as old and nothing is done.

A link-state request is performed to increase the sequence number.

A default route on router R2 to router R1.

A default route on the PC to router R2.

A static route on the PC to router R2 and a static route on router R2 to the PC.

A default route on router R1 to router R2.

Router LSA

Network LSA

Intra-Area Prefix LSA

Link LSA

When link-state information reaches the maximum age on a router, the router will flood that information to its neighbors.

When a router detects that any of its link-state information has reached the maximum age, it will request a new update from the source router.

Aging helps ensure that links, which are no longer part of the topology, will eventually get removed from the LSDB.

The age value is updated as the information is flooded throughout the network and when it is in the LSDB.

One.

One for each of the routers in area 0

One for each of the external routes exported by router R1.

Type 4 LSAs are not generated in this network topology.
