Deleting groups

To delete a group, the neighbor configurations must first be shut down. After each neighbor shuts down, you must shut down the group before issuing the no group namecommand.

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
Example
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

Trying to delete the group without shutting it down results in the following message:

ALA-B>config>router>bgp# no group headquarters1
MINOR: CLI BGP Peer Group should be shutdown before deleted. BGP Peer Group not 
deleted.
