MP-472
Cisco IOS Multiprotocol Label Switching Command Reference
January 2010
show ip bgp neighbors policy: Example
The following sample output shows the policies applied to the neighbor at 192.168.1.2. The output
displays both inherited policies and policies configured on the neighbor device. Inherited polices are
policies that the neighbor inherits from a peer-group or a peer-policy template.
Router# show ip bgp neighbors 192.168.1.2 policy
Neighbor: 192.168.1.2, Address-Family: IPv4 Unicast
Locally configured policies:
route-map ROUTE in
Inherited polices:
prefix-list NO-MARKETING in
route-map ROUTE in
weight 300
maximum-prefix 10000
Cisco IOS Release 12.0(31)S and 12.4(4)T: Example
The following is sample output from the show ip bgp neighbors command that verifies that
Bidirectional Forwarding Detection (BFD) is being used to detect fast fallover for the BGP neighbor that
is a BFD peer.
Router# show ip bgp neighbors
BGP neighbor is 172.16.10.2, remote AS 45000, external link

Using BFD to detect fast fallover
Cisco IOS Release 12.2(33)SRA: Example
The following is sample output from the show ip bgp neighbors command that verifies that BGP TCP
path maximum transmission unit (MTU) discovery is enabled for the BGP neighbor at 172.16.1.2.
Router# show ip bgp neighbors 172.16.1.2
BGP neighbor is 172.16.1.2, remote AS 45000, internal link
BGP version 4, remote router ID 172.16.1.99

For address family: IPv4 Unicast
BGP table version 5, neighbor version 5/0

Address tracking is enabled, the RIB does have a route to 172.16.1.2
Address tracking requires at least a /24 route to the peer
