To delete a group, the neighbor configurations must be shut down first. After each neighbor is shut down, you must shut down the group before issuing the no group name command.
Use the following syntax to shut down a peer and neighbor and then delete a group.
config>router# bgp
no group name
shutdown
no neighbor ip-address
shutdown
shutdown
config>router# bgp
config>router>bgp# group headquarters1
config>router>bgp>group# neighbor 10.0.0.105
config>router>bgp>group>neighbor# shutdown
config>router>bgp>group>neighbor# exit
config>router>bgp>group# neighbor 10.0.0.103
config>router>bgp>group# shutdown
config>router>bgp>group# exit
config>router>bgp# no headquarters1
If you try to delete the group without shutting down the peer-group, the following message appears.
ALA-B>config>router>bgp# no group headquarters1
MINOR: CLI BGP Peer Group should be shutdown before deleted. BGP Peer Group not
deleted.
