Display information about BGP neighbors.

Procedure

To enter User EXEC mode, log on to the switch.
Display information about BGP neighbors:

show ip bgp neighbors [{A.B.C.D}] [vrf WORD<1–16>] [vrfids WORD<0–512>]
Display information about BGP peer advertised routes:

show ip bgp neighbors {A.B.C.D} advertised-routes [<prefix/len>] [longer-prefixes] [vrf WORD<1–16>] [vrfids WORD<0–512>]
Display information about BGP peer routes:

show ip bgp neighbors {A.B.C.D} routes [<prefix/len>] [community <enable|disable>] [longer-prefixes] [vrf WORD<1–16>] [vrfids WORD<0–512>]
Display statistics for BGP peers:

show ip bgp neighbors {A.B.C.D} stats [vrf WORD<1–16>] [vrfids WORD<0–512>]

Variable Definitions

The following table defines parameters for the show ip bgp neighbors command.


Variable	Value
{A.B.C.D}	Specifies the IP address.
community <enable\|disable>	Enables or disables the display of community attributes.
longer-prefixes	Shows long prefixes. The longer-prefixes indicate the mask length from a specified prefix to 32 (for example, show from prefix a.b.c.d/len to a.b.c./32).
prefix/len	Shows paths with this prefix. The prefix is the IP address and exact mask length (must be an integer value from 0–32).
vrf WORD<1–16>	Specifies a VRF instance by name.
vrfids WORD<0–512>	Specifies a range of VRFs by ID number.
