Question:

A network administrator is configuring a BGP router with the neighbor 10.12.1.2 maximum-prefix 10 command. What will happen when the peer at 10.12.1.2 advertises more than 10 routes?

  • The router drops any further advertisements from the peer.
  • The router sends a warning message to the peer.
  • The router closes the BGP session for 30 seconds and then restarts the BGP peering process.
  • The router moves the peer to the Idle state and closes the BGP session.

Explanation: The prefix restrictions can be put on a BGP neighbor by using the BGP address family configuration command neighbor ip-address maximum-prefix prefix-count [ warning-percentage ] [ restart time ] [ warning-only ]. When a peer advertises more routes than the maximum prefix count, the router moves the neighbor to the Idle (PfxCt) state in the finite-state machine (FSM), closes the BGP session, and sends out the appropriate syslog message.
