I have three OSPF areas connected via OSPF "0" backbone and there is MPLS VPN created.
Iside each area is L3 switch c3550 which acts as gateway for VLAN in VRF (CE). The switch is for the purpose of VPN connected to MPLS backbone (PE) through IPIP tunnel. In the VRF inside OSPF area is only very simple static routing - on L3 switch the default route is directed to the tunnel.
The MPLS VPN itself seems to be working fine - I can reach each L3 switch or router inside VPN - but only from other router/switch.
After connecting PC into VLAN inside VRF, it can?t reach even its gateway - well I handle this with "sdm prefer extended-match". Very tricky btw.
After that correction the PC can reach its gateway, and it even can reach "beginnig" of IPIP tunnel on L3 switch, but not anything else inside VPN, not even the "other" side of tunnel on PE router. From VPN I can reach PC?s gateway, but not PC itself.
When I connect PE and CE via 802.1q trunk and move gateway of VLAN in VRF to the PE, everything work just fine. So I believe the problem lies somewhere in L3 switch, maybe with cooperation with IPIP tunnel.
