HSRP Problem

i have two cisco 4507 Switches one is acting as VTP server and switch 2 is client.

Both switch are trunk and i have confiugred the layer 2 Ether Channel on these two trunks.

I have around 7 vlans on switches and for each vlan i made a SVI and also configure these VLAN as HSRP.

switch 1 all vlan interfaces are active and switch 2 vlans are in standby mode. my active fw is connected

with switch one and failover is connected with switch 2.

user subnet is connected with vlan 7 and physical terminated on switch 1 ports 4/17 to 4/20 and having default gateway

of HSRP IP of VLAN 7, which is 172.28.31.163.

NOw problem is that, when switch one vlan 7 SVI goes down, and user is not able to reach any network.

though the gateway is virutal iP but still user is not able to reach anything.

Switch 1:

interface Vlan2

description ### To PDC-OUT-525-1 ###

ip address 172.28.31.65 255.255.255.248

standby 10 ip 172.28.31.67

standby 10 priority 250

standby 10 preempt

!

interface Vlan3

description ### TO PDC-Int-525-1 ###

ip address 172.28.31.81 255.255.255.248

standby 10 ip 172.28.31.83

standby 10 priority 250

standby 10 preempt

interface Vlan7

standby 10 preempt

Switch 2:

interface Vlan2

standby 10 priority 200

standby 10 preempt

!

interface Vlan3

description ### TO PDC-Int-525-2 ###

ip address 172.28.31.82 255.255.255.248

standby 10 ip 172.28.31.83

standby 10 priority 200

standby 10 preempt

interface Vlan7

description ### To NOC###

ip address 172.28.31.162 255.255.255.248

standby 10 ip 172.28.31.163

standby 10 priority 200

standby 10 preempt

please tell me how to provide the redundency and how to configure it and what is missing in my configuration

Re: HSRP Problem

Wasiimcisco,

I'm not sure if it as typo or not but the subnet masks are not the same for vlan 7. If you correct the mask on both switches things should work.
