HSRP B/W Layer Devices

Can HSRP work between to layer 3 devices?

If I have (2) 6000 Layer 3 Catalyst switches and (2) 7500 series routers. I want to connect each 6000 switches to 7500 routers. For Example, I can connect (2) 6009A/6009B to 7507A/7507B via subnets 172.16.10.0/24, and 172.16.20.0/24.

Configs:

6009A:

int vlan 10

ip address 172.16.10.2 255.255.255.0

standby 10 ip addres 172.16.10.1

standby 10 priority 110

standby 10 preempt

int vlan 11

ip address 172.16.11.3 255.255.255.0

standby 11 ip address 172.16.11.1

standby 11 priroity 100

6009B

int vlan 10

ip address 172.16.10.3 255.255.255.0

standby 10 ip addres 172.16.10.1

standby 10 priority 100

int vlan 11

ip address 172.16.11.2 255.255.255.0

standby 11 ip address 172.16.11.1

standby 11 priroity 110

standby 11 preempt

7500A

int E6/0

ip address 172.16.10.4 255.255.255.0

int E6/1

ip address 172.16.11.4 255.255.255.0

7507B

int E6/0

ip address 172.16.10.5 255.255.255.0

int E6/1

ip address 172.16.11.5 255.255.255.0

Will it work? I don't know if HSRP can work between (2) Layer 3 device.

Thanks

Yes, that will work. HSRP is supported in the MSFC and the 7500.

Re: HSRP B/W Layer Devices

Since you mentioned it will work fine. I have one more question. Can I run HSRP bidirectional between 6500s and 7500s? In my current configuration, if one of the 6500s fails the other 6500 will take over depend on vlan though, but if one of th 7507s fails, then there is no redundancy. Rightnow, 7500s are not connected with each other, but if I do so then I could also run HSRP on both 7500s as well as 6500s. In this case, it wouldn't matter whether 6500 fails or 7500s fails, the traffic should go through alternate route.

Thanks,

Ali
