Use display bgp peer to display BGP peer or peer group information.

Syntax

display bgp [ instance instance-name ] peer ipv4 { multicast | [ unicast ] [ vpn-instance vpn-instance-name ] } [ ipv4-address mask-length | { ipv4-address | group-name group-name } log-info | [ ipv4-address ] verbose ]

display bgp [ instance instance-name ] peer ipv6 { multicast | [ unicast ] [ vpn-instance vpn-instance-name ] } [ ipv6-address prefix-length | { ipv6-address | group-name group-name } log-info | [ ipv6-address ] verbose ]

display bgp [ instance instance-name ] peer { ipv4 | ipv6 } [ unicast ] vpn-instance-all [ verbose ]

Parameters

instance instance-name: Specifies a BGP instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify this option, the command displays BGP peer or peer group information for the default BGP instance.

ipv4: Displays IPv4 BGP peer or peer group information.

ipv6: Displays IPv6 BGP peer or peer group information.

link-state: Displays BGP LS peer or peer group information.

multicast: Displays BGP multicast peer or peer group information.

unicast: Displays BGP unicast peer or peer group information.

vpn-instance-all: Displays BGP peer or peer group information for all VPN instances.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command displays BGP peer or peer group information for the public network.

ipv4-address mask-length: Specifies a subnet. The value range for the mask length is 0 to 32. If you specify a subnet, this command displays information about all dynamic peers in the subnet.

ipv4-address: Specifies a peer by its IPv4 address.

ipv6-address prefix-length: Specifies a subnet. The value range for the prefix length is 0 to 128. If you specify a subnet, this command displays information about all dynamic peers in the subnet.

ipv6-address: Specifies a peer by its IPv6 address.

group-name group-name: Specifies a peer group by its name, a case-sensitive string of 1 to 47 characters.

log-info: Displays log information.

verbose: Displays detailed information. If you do not specify this keyword, the command displays brief peer information.

Usage guidelines

If you do not specify any parameters, this command displays brief information about all BGP peers for the specified address family.

By default, the unicast keyword is used if the unicast and multicast keywords are not specified.
