hsrp goes through various states to obtain the active role... according to david hucaby in the ccnp switch ocg we have:
When HSRP is configured on an interface, the router progresses through a series of states before becoming active. This forces a router to listen for others in a group and see where it fits into the pecking order. Devices participating in HSRP must progress their interfaces through the following state sequence:
1. Disabled
2. Init
3. Listen
4. Speak
5. Standby
6. Active
2. Init
3. Listen
4. Speak
5. Standby
6. Active
whoa... according to rfc 2281 we have...
All routers begin in the Initial state. This section discusses the
intent of each state. For specific details on the actions taken in
each state, please see the state transition table in section 5.7.
1. Initial
This is the starting state and indicates that HSRP is not running.
This state is entered via a configuration change or when an
interface first comes up.
2. Learn
The router has not determined the virtual IP address, and not yet
seen an authenticated Hello message from the active router. In
this state the router is still waiting to hear from the active
router.
3. Listen
The router knows the virtual IP address, but is neither the active
router nor the standby router. It listens for Hello messages from
those routers.

RFC 2281 Cisco HSRP March 1998
4. Speak
The router sends periodic Hello messages and is actively
participating in the election of the active and/or standby router.
A router cannot enter Speak state unless it has the virtual IP
address.
5. Standby
The router is a candidate to become the next active router and
sends periodic Hello messages. Excluding transient conditions,
there MUST be at most one router in the group in Standby state.
6. Active
The router is currently forwarding packets that are sent to the
group's virtual MAC address. The router sends periodic Hello
messages. Excluding transient conditions, there MUST be at most
one router in Active state in the group.
i hate when that shit happens...
then from cisco.com we have...
http://www.cisco.com/en/US/docs/ios/12_1t/12_1t3/feature/guide/dt_hsrpi.html
here there is learn, but no mention of disabled... in all 3 cases there are six states...
and finally...
http://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gthsrpv2.html
initial and disabled got married in the fourth one...
would someone please try to get these people together...
