Hi,
we planned to run HSRP on our BGP router which is state is not changing fron learning to any state both of the routers are in learning state only
the network digram in attached as an attachment
when i debug i see the message as
on primary is seen as
*Oct 8 06:45:03.119: HSRP: Gi0/3 interface adv out, Passive, active 0 passive 2
*Oct 8 06:45:04.651: HSRP: Gi0/3 interface adv in, Passive, active 0, passive 1, from xxx.xx.44.38

on secondary

were will be the problem and moreover we are using 3 com l2 switch for wan connectivity and giving uplink for HSRP
is it correct way
pls advice

Hi,
I met similar problem in the past.
HSRP Hello frames are multicasts.
And some 3Com switches don't forward multicasts by default.
So I had to enable multicast forwarding on 3Com switches to make HSRP working.
Possibly you are in the same trouble?

Hi,
to be frank, I don't understand that debug messages. They seem to show you are receiving HSRP Hellos from both sides.
So I might have been wrong and the problem is not the 3Com switch.
Another idea:
You are using
standby ip ... secondary
on both routers, aren't you?
I've got a feeling this might be incorrect, as I've found an explanation saying the secondary keyword does not mean "use secondary IP address" (as I'd expect) but "become a secondary HSRP router" (should be used if no HSRP priority was configured).
The example in
http://www.cisco.com/en/US/products/ps6600/prod_bulletin09186a00800a3d9e.html
is pretty confusing, as using "secondary" only on one router.
I made a quick test on one of my routers and it seems I'm correct.
So try to remove the "secondary" option from your "stanby ip ..." commands and your HSRP might start working.

In the drawing I noticed that your standby IP's(xx.58.141.254) are not in the same subnet as the interfaces (xx.58.41.252 or 253).

Hi,
Sorry its mistakely written
xx.58.141.252 or 253)
thanks any advice on this issue

Compare the 'show HSRP detail' command results for each device. That might give you some more info.

Hi,
can you paste here the whole HSRP config section from both your routers?
BR,

the config
RTR-PRI:

Hi,
have you tried to remove the "sedcondary" option from
standby 30 ip XX.58.141.254 secondary
standby 30 ip XX.58.141.254 secondary
commands?

Hi,
on both the router

Vinoth, can you ping the secondary addresses from one another? This will have to be done using an extended ping sourcing your secondary IP address. I noticed that the primary IP addresses of both routers are in two different subnets which suggests that interface gi0/3 on both routers are not in the same vlan.
