Configures an existing neighbor as the member of a peer group.
| all | Specifies all neighbors. |
| remoteaddr | Specifies the IPv4 or IPv6 address of a BGP neighbor. |
| peer-group-name | Specifies a peer group name. |
| none | Removes the neighbor from the peer group. |
| acquire-all | Specifies that all parameters should be inherited by the neighbor from the peer group. |
By default, remote AS (if configured for the peer group), source-interface, outbound route policy, send-community and next-hop-self settings are inherited.
This command applies to the current VR or VRF context.
If acquire-all is not specified, only the default parameters are inherited by the neighbor.
When you remove a neighbor from a peer group, it retains the parameter settings of the group. The parameter values are not reset to those the neighbor had before it inherited the peer group values.
To create a new neighbor and add it to a BGP peer group, use the following command:
create bgp neighbor remoteaddr peer-group peer-group-name {multi-hop}The new neighbor is created as part of the peer group and inherits all of the existing parameters of the peer group. The peer group must have a remote AS configured.
If you are adding an IPv4 peer to a peer group and no IPv4 address family capabilities are assigned to the specified peer group, the IPv4 unicast and multicast address families are automatically enabled for that peer group. If you adding an IPv6 peer to a peer group and no IPv6 address family capabilities are assigned to the peer group, you must explicitly enable the IPv6 address family capabilities you want to support.
Note
If the peer group or any member of the peer group has been configured with an IPv4 or IPv6 address family, the peer group only accepts peers that are configured to use that family. For example, if a peer group is configured for the IPv4 unicast address family, the switch will not allow you to add an IPv6 peer. LIkewise, an IPv6 peer group cannot accept an IPv4 peer.
The following command configures an existing neighbor as the member of the peer group outer:
configure bgp neighbor 192.1.1.22 peer-group outer
This command was first available in ExtremeXOS 10.1.
This command required a specific license in ExtremeXOS 11.1.
Support for IPv6 was added in ExtremeXOS 12.6 BGP.
This command is available on platforms that support the appropriate license. For complete information about software licensing, including how to obtain and upgrade your license and which licenses support the BGP feature, see the Feature License Requirements document.
