A network administrator issues the show bgp ipv4 unicast summary command on a router to check the adjacency state with a neighbor router. The value under the State/PfxRcd field shows 0. Which statement describes the status of adjacency between the two routers?

A network administrator issues the show bgp ipv4 unicast summary command on a router to check the adjacency state with a neighbor router. The value under the State/PfxRcd field shows 0. Which statement describes the status of adjacency between the two routers?

• The adjacency is successfully formed.
• The adjacency is formed, but no message is transmitted.
• Because the neighbor command is wrong, the adjacency is not formed.
• Because there is no Layer 3 connectivity between the two routers, the adjacency is not formed.

Explanation: The State/PfxRcd indicates the current state of the BGP peer or the number of prefixes received from the peer. A value of 0 or another number indicates that the adjacency is successfully formed. The value indicates the number of prefixes received from the neighbor. Messages received and sent between routers are indicated under the MsgRcvd and MsgSent fields. BGP uses TCP to communicate. If there is Layer 3 connectivity, the state value is Idle. If Layer 3 connectivity exists and a three-way TCP handshake is complete, an open message is sent. However, if there is no response to the open message, the state value is Active.
