I have two 837s running HSRP. Both routers are connected to a 2960.
Router_1:
interface Ethernet0
ip address 192.168.0.2 255.255.255.0
no ip redirects
standby 1 ip 192.168.0.1
standby 1 timers 254 255
standby 1 priority 111
standby 1 preempt
hold-queue 100 out
Router_2:
interface Ethernet0
ip address 192.168.0.3 255.255.255.0
no ip redirects
standby 1 ip 192.168.0.1
standby 1 timers 254 255
standby 1 priority 222
standby 1 preempt
hold-queue 100 out
I have noticed the following:
A) when I ping from Router_2 to the Switch all the packets come back fine BESIDES when I the Router is receiving HSRP messages. This is causing the Router loose one packet and that is why I have modified the Standby timer to send as little as possilbe...i.e.
Router_2#ping 192.168.0.4
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.0.4, timeout is 2 seconds:
*Apr 4 22:49:18.774: HSRP: Et0 Grp 1 Hello out 192.168.0.3 Active pri 222 vIP 192.168.0.1
*Apr 4 22:49:19.790: HSRP: Et0 Grp 1 Hello in 192.168.0.2 Standby pri 111 vIP 192.168.0.1.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 1/1/1 ms
_______________________________________
The same happens when this message is received, but I don't quite understand what the message is about
Router_2#ping 192.168.0.4
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.0.4, timeout is 2 seconds:
*Apr 4 22:49:08.338: HSRP: Et0 REDIRECT adv in, Passive, active 0, passive 1, from 192.168.0.2.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 1/1/4 ms
____________________________________
in both cases I don't understand why these messages are affecting my pinging???
B) when I ping from the Switch to the virtual ip address the results are totally random...

any ideas on what is happening???
