show ip bgp neighbors
MP-463
Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
Usage Guidelines Use the show ip bgp neighbors command to display BGP and TCP connection information for neighbor
sessions. For BGP, this includes detailed neighbor attribute, capability, path, and prefix information. For
TCP, this includes statistics related to BGP neighbor session establishment and maintenance.
Prefix activity is displayed based on the number of prefixes that are advertised and withdrawn. Policy
de
nials display the number of routes that were advertised but then ignored based on the function or
attribute that is displayed in the output.
Cisco IOS Releases 12.0(25)S, 12.4(11)T, 12.2(33)SRB, and Later Releases
When BGP neighbors use multiple levels of peer templates, it can be difficult to determine which
policies are applied to the neighbor.
In Cisco IOS Releases 12.0(25)S, 12.4(11)T, 12.2(33)SRB and later releases, the po
licy and detail
keywords were added to display the inherited policies and the policies configured directly on the
specified neighbor. Inherited policies are policies that the neighbor inherits from a peer-group or a
peer-policy template.
12.0(21)ST The output was modified to display Multiprotocol Label Switching (MPLS)
l
abel information.
12.0(22)S Support for the BGP graceful restart capability was integrated into the
out
put. Support for the Cisco 12000 series routers (Engine 0 and Engine 2)
was also added.
12.2(14)S This command was integrated into Cisco IOS Release 12.2(14)S.
12.2(15)T Support for the BGP graceful restart capability was integrated into the
out
put.

licy and detail keywords were added.
12.2(17b)SXA This command was integrated into Cisco IOS Release 12.2(17b)SXA.
12.0(27)S The command output was modified to support the BGP TTL Security Check
f
eature and to display explicit-null label information.
12.3(7)T The command output was modified to support the BGP TTL Security Check
f
eature and to display explicit-null label information.
12.0(31)S Support for the Bidirectional Forwarding Detection (BFD) feature was
in
tegrated into the output.
12.2(18)SXE Support for the Bidirectional Forwarding Detection (BFD) feature was

licy and detail keywords was integrated into
Cisco IOS Release 12.4(11)T.
