FWSM problems with OSPF and VLANs
We are trying to configure OSPF on our new Firewall Services Modules(running 2.3(1)) on a Cat6k's. The FWSM are configured for single context routed mode, allowing it to route between VLANs.
Each VLAN has been defined on the MSFC and is mapped to the FWSM, with 1 active VLAN for the connection between the MSFC and FWSM. The VLAN layer 3 interfaces (or SVIs) are created on the FWSM and become active - even when there is no physical connection on the cat6k UTP port to the VLAN.
To my mind the layer 3 interface should not become active - and start advertising itself in OSPF - until the physical connection to the UTP port and VLAN becomes active (this is the case when configuring the VLANs on an MSFC). The consequences of this are that the FWSM advertises routes across the network to the defined VLANs even though there's no active connection.
Could anyone shed any light on the best way to solve this? Any help is appreciated.
