HSRP issue with L3 switches

sidris-sid · ‎04-06-2011

Hi ,

I’m facing strange issue with HSRP, I configure HSRP between two Core switches “3750 =Core 1 & 3560 =Core 2” I tried to load sharing between the two switches, for instance VLAN9 be active in Core1 & standby in core 2 other VLan active in Core 2 standby Core1 ….the issue that I’m facing is when I ping server within VLAN 9 is pinging only if VLAN 9 is active within Core2 even if the server is directly connected to Core 1 …..Already there is trunk between the two switches “Etherchannel”

Here is my Config:

Core1:

interface Vlan9

ip address 192.168.9.252 255.255.255.0

standby 1 ip 192.168.9.254

standby 1 preempt

standby 1 priority 95

standby 1 track GigabitEthernet1/0/33

standby 1 track GigabitEthernet1/0/34

Core2:

interface Vlan9

ip address 192.168.9.253 255.255.255.0

standby 1 ip 192.168.9.254

standby 1 preempt

standby 1 track GigabitEthernet0/33

standby 1 track GigabitEthernet0/34

According to your configuration for VLAN 9, Core-2 will be the primary and Core-1 will be in standby. The default priority for HSRP is 100 and the higher the priority takes over. So, putting the priority at 95 on Core-1 and leaving the default priority on Core-2 will cause Core-2 to answer your requests.

Change the priority on Core-1 to something higher than 100 and I think you'll see what you are looking for.

If you have a trunk link between those 2 switches you should be able to ping it . If not my guess would be the server default gateway is not pointed to the HSRP virtual address (192.168.9.254) as the gateway.
