we have 2 * 6500 series core switches with each FWSM installed.
There are some user VLANs (per floor) and lots of servers inside that belong to some other VLANs.
The core switches have been configured with HSRP redundancy (active/passive).
Nowadays i am challenging with FWSM configuration in routed mode.
There is no problem with typical configuration and tests,
i mean assigning VLANs to FWSM and removing IP adresses from MSFC.
But unfortunately whenever i do such a configuration, i naturally lose redundancy between the switches.
In our situation HSRP is a must.
Is there any way to solve this design issue in routed mode with HSRP support.?
Juergen is absolutely right. As long as you have a default route on your FWSM pointing to the MSFC then you can leave the statics as is.
So your FWSM has multiple vlans that it is protecting. You then connect the outside interface of your FWSM to the MSFC with L3 SVI and then your default route on the FWSM points to the L3 SVI.
Depending on whether you are running a routing protocol on the FWSM you may need to add static for the subnets behind your FWSM to the 6500 switch.
(correct me if I'm wrong, Jon) - If you delete all SVIs you need of course route all traffic on the FWSM.
What we did was to create a transfer network (VLAN) with a SVI and the outside FWSM interface in it. Now the default gateway on the FWSM is set to the IP address of this SVI. So most of the routing is configured on the switch.
