JUNOSe 9.1.x Command Reference Guide N to Z > N Commands > neighbor peer-group

neighbor peer-group

Description: 

When used from Router Configuration mode without specifying an IP address, creates a BGP peer group. The no version removes a peer group.

When used from Router Configuration mode with an IP address or from Address Family Configuration mode, configures a BGP neighbor to be a member of a peer group. The no version removes a neighbor from a peer group.

NOTE: You cannot mix IPv4 and IPv6 peer members in a peer group. Only one type peer is allowed, IPv4 or IPv6. For example, the following error is generated if an IPv6 peer group member is added to a peer group that already has IPv4 members; that is, where the peer-group type is IPv4: host1(config-router)#neighbor 1::1 peer-group hamburg % Unable to set 'peer-group' for address family ipv4:unicast for peer 1::1 in core (IPv6 peer cannot be member of a peer-group of type IPv4)

Syntax: 

Creating a peer group:

neighbor peerGroupName peer-group

no neighbor peerGroupName [ peer-group ]

• peerGroupName—Name of BGP peer group

Assigning members to a peer group:

neighbor { ipAddress | ipv6Address } peer-group peerGroupName

no neighbor { ipAddress | ipv6Address } peer-group [ peerGroupName ]

• ipAddress—IP address of the BGP neighbor that belongs to the peer group specified by the name
• ipv6Address—IPv6 address of the BGP neighbor that belongs to the peer group specified by the name
• peerGroupName—Name of the BGP peer group to which this neighbor belongs
