Information About GLBP

GLBP provides path redundancy for IP by sharing protocol and Media Access Control (MAC) addresses
between redundant gateways. Additionally, GLBP allows a group of Layer 3 routers to share the load of
the default gateway on a LAN. A GLBP router can automatically assume the forwarding function of
another router in the group if the other router fails.
