Hi, i have an MPLS network using BGP to advertise routes. i also have an IPSEC VPN (via ASA) that i want to be a backup. i have tried configuring OSPF on the core switch and getting the MPLS CPE to redistribute into OSPF but no luck. idea being core switch has learnt routes when MPLS working, MPLS down -> routes removed and default route to ASA takes over.
network topology:
Cisco 2921 (MPLS)
/
LAN -> Core Switch
\
Cisco ASA
switch is default gateway and has 2 vlans (1 for MPLS and other for LAN/ASA) it has a default route pointing to ASA
what i have configured:
MPLS:
router ospf 10
log-adjacency-changes
redistribute bgp 42 subnets
redistribute connected subnets
!
router bgp 42
bgp log-neighbor-changes
bgp redistribute-internal
no synchronization
neighbor 192.168.229.2 remote-as 69
redistribute static
!
Core:
router ospf 10
log-adjacency-changes
network 10.44.0.0 0.0.255.255 area 1
network 172.16.200.0 0.0.0.255 area 0
!
the MPLS has the BGP routes fine but i cant get the switch to see them, any help much appreciated

You have no "network .."statement under your OPSF configuration on the MPLS router.
The connection from the MPLS router to the core switch, what subnet is that ? You need to have a -
network x.x.x.x
for the subnet on both the MPLS router and the core switch.
