Hi Guys,
I have a strange issue on HSRP. Has anyone encountered such an issue before ? I had to shutdown the standby switch so I made sure all the vlans are active on the primary switch. On reboot of secondary switch, Vlan 23 below which was active on the primary switch went from Active to Init state and remained in that state till the secondary switch came back up.
Actually there were 12 vlans out of which 4 got stuck in Init, the others remained active. I have truncated the config and am focusing only on the below 3 vlans which depict the whole scenario else mentioning all the 12 Vlans was making the whole explanation below too long. Do let me know if you need any more information.
