neighbor peer-group

This command creates a BGP peer group and adds a peer group neighbor.

Syntax

neighbor groupID peer-group
no neighbor groupID peer-group
neighbor ip-address peer-group groupID
no neighbor ip-address peer-group groupID

Parameters

ip-address An IPv4 or IPv6 address to add to a peer group. IPv4 addresses are specified in dotted-quad format; IPv6 addresses are specified in colon-separated format.
groupID Specifies a BGP peer group name as a character string. If an invalid IP address is specified (for example, 256.1.1.1), it will be read as a group name.

Defaults

None.

Mode

BGP Router Configuration.

Usage

The neighbor groupID peer-group command creates a peer group. BGP peers can then be added to that group. After this command is issued, peers are added to the group using the neighbor ip-address peer-group command. All members of the peer group must be of the same peer type: IBGP, EBGP or EBGP confederation.

Peer group commands are policy related. If a peer is in a peer group, and both the peer and peer group have policy configured, the peer group‘s policy takes precedence for route export. The peer‘s policy takes precedence for route import.

Example

The following example configures peer group abc with peers 1.2.3.4 and 4.3.2.1 added to it.

System(su-config)->router bgp 65151
System(su-config-bgp)->bgp router-id 1.1.1.1
System(su-config-bgp)->neighbor 1.2.3.4 remote-as 65151
System(su-config-bgp)->neighbor 4.3.2.1 remote-as 65151
System(su-config-bgp)->neighbor abc peer-group
System(su-config-bgp)->neighbor 1.2.3.4 peer group abc
System(su-config-bgp)->neighbor 4.3.2.1 peer-group abc
