I am trying to remove VLAN 11 (10.10.30.1 /26), 12 (10.10.30.65 /26) and 13 (10.10.30.129 /26) from the core and place them on a firewall (changing from L3 VLANs on core to L2).
The problem I am having is when putting in a static route, OSPF isn't updating and this is causing the traffic to expire in transit as it is trying to reach the gateway on the core which has been moved to the firewall as an interface to a /26 range.
I find this description of the problem to be not clear. Have the SVIs for vlan 11 and 12 and 13 been removed from the core? As long as the SVIs exist and OSPF does redistribute static then the /26 subnets will still be in the routing table and will be used and not the /24 static.
