OSPF Route v IPSEC VPN

Hello all.

Could anyone point me in the right direction regarding the dilema below.

I have a pair of ASA 5510's running with VLAN Sub-interfaces. For simplicity i'm going to label them 1.3 (192.168.12.0/24) and 1.16 (172.16.100.0/24)

Connected to VLAN.3 is a 2801 Router that is advertising an OSPF route to 172.20.0.0/16 via 192.168.12.253 (MPLS network). I can see this in the routing table on the ASA.

However, I have to configure a new Site-to-Site VPN for a client on VLAN16, which as it would happen, use 172.20.0.0/16 at the remote end. The local networks are segregated and I do not have the 'Same Sec permit' enabled.

When I run a packet tracer from the VLAN16 Network, to 172.20.0.0/16 I can see its trying to egress out of 192.168.12.253.

The million dollar question is am I able to get this Site-to-site to 'ignore' the entry in the routing table and go out via the 'Outside' interface?

You can probably tell I'm a total novice so any assistance would be appreciated.

Thanks.
