Hi group,
I googled this but did not find a definitive answer.
Is it possible to have HSRP on an interface of a Cisco, with just the virtual IP address, not a "real" IP address?
I'm asking because a consultant is setting up a new network for us, insisting on many /24 segments. Each of these segments will be routed through a collapsed backbone setup and will probably use HSRP.
Although loosing two addresses in a /24 is not a big deal, I want to know if it is possible, and if it is, is it a good idea.
(Actually due to DHCP redundancy, only half of the addresses can be used, which would mean 125 instead of 126 possible addresses. Whatever)
As far as I can tell, it is simply not possible. IOS simply does not allow it. The 'standby ip' command does not allow a netmask so is tied to the 'ip address' command.
Any thoughts?
