A group must be shut down first to delete it.
Use the following syntax to shut down and then delete a group.
config>router# rip
[no] group group-name
shutdown
config>router# rip
config>router>rip# group "RIP-ALA-3"
config>router>rip>group# shutdown
config>router>rip>group# exit
config>router>rip# no group "RIP-ALA-33"
If you try to delete the group without shutting it down first, the following message appears:
INFO: RIP #1204 group should be administratively down -
virtual router index 1,group RIP-ALA-4
