can't ping hsrp ip address

I have 2 routers, R1 is a 3725 & R2 is a cisco 2651XM. Dual HSRP is set up between both and those ip addresses are x.x.x.1 & x.x.x.2. The basic set up of the interfaces looks like this.

R1

interface FastEthernet0/1

ip address x.x.x.3 255.255.255.0

standby 1 ip x.x.x.1

standby 1 priority 120

standby 1 preempt

standby 2 ip x.x.x.2

standby 2 preempt

R2

interface FastEthernet0/1

ip address x.x.x.4 255.255.255.0

standby 1 ip x.x.x.1

standby 1 preempt

standby 2 ip x.x.x.2

standby 2 priority 120

standby 2 preempt

The thing that I can't work out is that R2 can ping x.x.x.1-4 but R1 can only ping x.x.x.1&3&4 it will not ping x.x.x.2. I have no idea why one router can ping both HSRP addresses and the other one can't.

Re: can't ping hsrp ip address

Can you provide the output from "show standby"?

Re: can't ping hsrp ip address

HSRP looks ok.

Can you try pinging the virtual .2 address aggress again from R1 and R2. Also get the show arp out put from each.

I'm assuming the config is pretty standard, no access-lists?

Re: can't ping hsrp ip address

I have tried pinging .2 from both Routers and the results are the same as before. The Fastethernet ports on both Routers have no ACL's applied. Below is the result from the "show arp".

From R1

Internet x.x.x.4 60 000f.f725.e9e1 ARPA FastEthernet0/1

Internet x.x.x.3 - 000d.28cc.6d91 ARPA FastEthernet0/1

Internet x.x.x.2 89 0000.0c07.ac02 ARPA FastEthernet0/1

Internet x.x.x.1 - 0000.0c07.ac01 ARPA FastEthernet0/1

From R2

Internet x.x.x.4 - 000f.f725.e9e1 ARPA FastEthernet0/1

Internet x.x.x.3 87 000d.28cc.6d91 ARPA FastEthernet0/1

Internet x.x.x.2 - 0000.0c07.ac02 ARPA FastEthernet0/1

Internet x.x.x.1 84 0000.0c07.ac01 ARPA FastEthernet0/1

I haven't dealt much with HSRP so I am unsure if the results that I keep seeing are normal or not.

Re: can't ping hsrp ip address

Hi,

Try using the extended ping with the source interface as Fa0/1. If this does not work also please post the show ip route output from both the routers.
