Possible to force switch to use static routes over directly conn
Thanks, I will try that. The reason I am trying to do this is because I have to migrate users from one switch to behind a FWSM. Normally if it was another switch I can set up HSRP on both switches and have a seamless migration.
A simplic view of my current topology is:
access switches <--trunk--> OLD 4500
Currently my switches are connected to an old 4500 with multiple SVIs. I was planning on dual connecting the access switches to my new 6500 and creating the SVIs on the FWSM. For the transition, I was thinking about having the same SVIs on both the 4500 and FWSM. For example both will have "int vlan 100" w/ different IP addresses and there will be a point to point link between the two switches for routing. I was going to change the DHCP settings to use the FWSM as the gateway once the workstation lease expires.
This is the problem I ran into. For example some VLAN 100 workstations renew their lease and use the FWSM as the gateway. They are trying to assess VLAN 150 still on the 4500. For example user VLAN 100, will go to the FWSM, out the outside interface to the 4500. Then the return traffic will not make it back because the 4500 will also have VLAN 100 and it is directly connected. The 4500 will do intervlan routing and never send anything to the FWSM.
But after thinking about this some more, I dont think this will work. Any ideas how I can do this with as little downtime as possible? Right now my new plan would be to just shutdown the SVI on the 4500 and turn on the SVI on the FWSM using the same IP address, so no need for DHCP leases, etc.. But this will cause downtime, even though it should be a few seconds.
