Ping is intermittent for a particular VLAN while doing HSRP with 3 catalyst
I've 3 catalyst connected between each other via etherchannel. My issue is this catalyst are doing HSRP. Let say my root is catalyst A having preempt priority 200, catalyst B priority 190 and catalsyt C priority 180. Now i have a problem with my vlan2 where the ping is intermittent. When i change my int vlan2 at Catalsyt A priority 170 (to make my Catalyst B as active for Vlan 2) then the ping is ok. All my other vlans are fine. Why?
Re: Ping is intermittent for a particular VLAN while doing HSRP
I'm using catalyst 6509 Version NmpSW: 7.1(1a) and MSFC2 version 12.1(3a)E4.
Problem Description: I've 3 catalyst 6509 connected between each other via etherchannel. This catalyst are doing HSRP. My root is catalyst hsbsc653 having preempt priority 200, catalyst hsbsc651 priority 190 and catalsyt hsbsc655 priority 180.
Now i have a problem with my vlan2 where the ping from user (User Gateway pointing to ip address 10.230.4.1 ) is intermittent. When i change my interface Vlan 2 at Catalsyt hsbsc653 priority 170 (to make my Catalyst hsbsc651 as active for interface Vlan 2) then the ping is ok. All my other vlans are working fine at hsbsc653. Why?
The problem start accuring after the migration of the floor access switch to catalyst 3508 and 2948G connected via Gbic port to core switches. Previously the connection to the core switch was on 100 FX.
Later I've upgrade switches 651 and 653 with the same Software Version: 12.1(3a)E4 on both MSFCs. Then we revert back the priority to 653. The ping the virtual ip address (10.200.126.1) from user PC still intermittent.
We even remove all the connection to the access switch leaving only the 3 catalsyt connected. I connect straight my Laptop to the catalsyt 653 and ping to the virtual ip. Still no luck, its intermittent.
We also remove the port channeling leaving only 1 GE connection between the 651, 653 and 655. Still no luck, its intermittent.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
