Reference Guide
show bfd neighbors
Displays information about BFD neighbors from all interfaces using the default VRF.
Syntax
show bfd neighbors [detail]
Parameters detail — (Optional) View detailed information about BFD neighbors.
Default Not congured
Command Mode EXEC
Usage Information Use the show bfd neighbors command to verify that a BFD session between neighbors is up using the
default VRF instance. Enter the details parameter to view the BFD session parameters.

Border Gateway Protocol
Border Gateway Protocol (BGP) is an interautonomous system routing protocol that transmits interdomain routing information within and
between autonomous systems (AS). The primary function of BGP is to exchange network reachability information with other BGP systems.
BGP adds reliability to network connections by using multiple paths from one router to another. Unlike most routing protocols, BGP uses
TCP as its transport protocol.
Autonomous systems
BGP autonomous systems are a collection of nodes under a single administration with shared network routing policies. Each AS has a
number, which an Internet authority assigns—you do not assign the BGP number.
