Q88. What is the source IP address in an OSPF update?

224.0.0.5

224.0.0.6

The unicast IP address of the interface the update is being sent on.

The system address of the router

Q89. What type of OSPF router generates a type 2 LSA?

Area Border Router

Autonomous System Boundary Router

Q90. What are some of the characteristics of Nokia’s implementation of non-stop routing? (Choose two)

No protocol extensions required

Only supported by OSPF and IS-IS

Q91. An interface is configured on a router for OSPF but the command “show router ospf neighbor” does not show any neighbors. Which of the following is NOT a possible cause?

Q93. How does a DMP inform the downstream routers that it has merged detour tunnels?

The DMP sends the DMP_Object in each detour’s PATH messages.

The DMP summarizes PATH messages, giving each detour its own MSGJD.

They must be recognized by all peers and optionally included in BGP updates.

The receiving router sends a notification if a well-known discretionary attribute is not present in an update.

Q96. Which of the following devices assumes the active role during the establishment of an LDP session?

The peer with the higher physical address.

The peer with the higher transport address.

The peer with the lower physical address.

The peer with the lower transport address.
