D) Using the Bellman-Ford algorithm, each OSPF router independently calculates its best paths to all destinations in the network.
E) When a link changes state, the router that detected the change creates a link-state advertisement (LSA) and propagates it to all OSPF devices using the 224.0.0.6 multicast address.
F) Using the DUAL algorithm, each OSPF router independently calculates its best paths to all destinations in the network.

2. Refer to the exhibit.

What happens when the router stops receiving advertisements for the 10.1.2.0/24 network?

A) The more specific routes will be advertised from the table.
B) 10.1.2.0/24 will still be advertised but packets destined for it will be dropped when they reach this router.
C) The summary route will remain in the table.
D) The summary route will be removed from the table.

3. If a metric is not specified for routes that are redistributed into OSPF, the default metric that is assigned to the routes is 20, except for redistributed BGP routes. What is the metric that is assigned to redistributed BGP routes?

B) Only redistributed RIP routes will appear in Area 1. They will be advertised via type 7 LSAs.
C) Redistributed RIP and IGRP routes will appear in Area 1. They will be advertised via type 5 LSAs.
