After the link failure, which of the following affects the routing protocol’s convergence time?
Refer to the exhibit. All routers in the diagram are running a link-state routing protocol. Before the link failure, all routers have operational adjacencies with each other and there is a BFD session between routers R1 and R3. After the link failure, which of the following affects the routing protocol’s...
What is the replacement for ARP in IPv6?
What is the replacement for ARP in IPv6?A . Duplicate address detection procedures.B . Router discovery procedures.C . Neighbor discovery procedures.D . Stateless address auto-configuration procedures.View AnswerAnswer: C Explanation: In IPv6, the Neighbor Discovery Protocol (NDP) replaces the Address Resolution Protocol (ARP) used in IPv4. NDP is responsible for several...

Assuming all links have the same cost, how many entries for prefix 192.168.3.0/24 will be in router R3’s routing table?
Refer to the exhibit. All routers in the diagram are running an interior gateway protocol (IGP) and have been configured with an ECMP value of 4. Router R5 advertises the prefix 192.168.3.0/24 using the IGP. Assuming all links have the same cost, how many entries for prefix 192.168.3.0/24 will be...
