We have a critical server that originally could not be routed to the DR server in our DR site. It had to be on the same subnet, so it was bridged to the DR site.
The server is using the BVI interface as it's default gateway.
We now need to remove this bridged subnet and put it on a routed subnet.
I am trying to come up with a plan to do this, while also understand how the bridge worked, as we still have the need to keep the two other existing bridged subnets.
As it stands now, there are three bridged subnets to DR.
I am thinking I could:
1. Create a subnet in DR for the DR server and make sure it is routing to HQ.
2.Configure HSRP on VLAN5 on our 6509 switches. It is not configured on this VLAN for some reason, don't know why.
3. Point the server to the VIP of HSRP pair for VLAN5.
Is this feasable while leaving the bridge configured to fall back on if there are problems?
Is there anything with the subinterfaces I need to take into account while I am doing this?
This is a DS3 point-to-point, but the configs are showing as Frame-Relay, is this a mock up of Frame-Relay, by using the "Frame-Relay Switching" command?
Why would the server use the BVI interface as it's default gateway and not the VLAN interface for that subnet?
Thanks for any information anyone can provide.
