Hi,
I am running VRRP on Cisco 2811 router (Cisco IOS Software, 2800 Software (C2800NM-ADVENTERPRISEK9-M), Version 12.4(15)T1), with another device.
i am getting following error message "VRRP: Header ip address count sanity check failed" on Cisco router, because of this Cisco router is always acting as Master even when priority of other device is more and other device is also acting as VRRP master.
The debug messages seen on Cisco 2811 router,
*May 2 12:13:37.043: VRRP: Grp 10 sending Advertisement checksum C9EB
*May 2 12:13:37.047: VRRP: Header ip address count sanity check failed
*May 2 12:13:39.995: VRRP: Grp 10 sending Advertisement checksum C9EB
*May 2 12:13:40.051: VRRP: Header ip address count sanity check failed
*May 2 12:13:42.783: VRRP: Grp 10 sending Advertisement checksum C9EB
*May 2 12:13:43.055: VRRP: Header ip address count sanity check failed
If i replace the Cisco with Juniper SSG 140 things are working with the same VRRP configuration.
Here is the information i need,
1. Why this error is coming on Cisco router
2. Do we have a solution for this issue
3. Or the other device is sending corrupted VRRP advertisiment packet
