GLBP Group Name
To enable IP redundancy by assigning a name to the Gateway Load Balancing Protocol (GLBP) group, use the glbp name command in interface configuration mode. To disable IP redundancy for a group, use the no form of this command.
The GLBP redundancy client must be configured with the same GLBP group name so the redundancy client and the GLBP group can be connected.
I have configured a glbp group on two LAN connected routers. One has a group name, one doesn't. It works fine. What is the meaning of this command?
