A BFD session can be set up in either static or dynamic mode.

A static BFD session is set up by manually configuring BFD session parameters and delivering requests for setting up a BFD session. BFD session parameters include the local and remote discriminators.

When the active interface goes down, the Smart Link group automatically blocks it and changes the status of the standby interface to active.

When the active interface recovers from a fault, traffic will be switched back to it immediately.

Which of the following are characteristics of a high availability network? (Choose two.)

Services can be quickly restored when a fault occurs.

Services can only be manually restored when a fault occurs.

The no-import-route parameter is used to prevent the importing of AS external routes in the form of Type-7 LSAs into an NSSA.

The no-summary parameter is used to prevent the advertisement of Type-3 and Type-4 LSAs in an area.

The set-n-bit parameter indicates that an N-bit will be set in a DD packet.
