The prefix list "reject" should be "192.168.3.0/16 exact".

Router R1 should be configured as an OSPF "asbr".

The policy was not "committed" after creation.

Router R1 cannot reject the route because OSPF does not support import policies

Data traffic from network 192.168.1.0/24 to 192.168.3.0/24 will be forwarded through router R2.

Data traffic from network 192.168 3.0/24 to 192.168.1.0/24 will be forwarded from router R3 directly to router R1.

The system interface of routers R1 and R3 must be included into OSPF for traffic to flow between the 192.168.1.0/24 and 192.168.3.0/24 networks.

The OSPF adjacency between router R1 and router R3 is operationally up.

Link

Intra-Area Prefix

Inter-Area Prefix

Inter-Area Router

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.

The ARP functionality has been replaced by the Neighbor Discovery protocol.

The ARP functionality is not needed due to the increased IPv6 address space.

ICMPv6 reduced its role to connectivity checking and auto-configuration only.

ICMFV6 replaced the ARP functionality with Multicast Listener Discovery (MLD).

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.
