HSRP

The Hot Standby Router Protocol (HSRP) provides high network availability by routing IP traffic from
hosts on Ethernet networks without relying on the availability of any single Layer 3 switch. This feature
is particularly useful for hosts that do not support a router discovery protocol and do not have the
functionality to switch to a new router when their selected router reloads or loses power.
For information on configuring HSRP, refer to the following URL:
