we have few sites connected over two different vpn tunnels one is over IPSec other is on plain GRE without IPSec due to ISP Constraints, both were working fine.
now some remote Locations connected to one ISP having problem at my VPN router.
i can reach remote location 1 from my core switch, but not to the other one, while i check the tunnels on vpn router bother up and can be reached through vpn router.
i am having rip between my vpn router and remote location and OSPF between core and vpn router.
the configuration is like
vpn router :
router ospf 10
redistribute rip subnets
network 192.168.1.0 0.0.0.255 area 0
distribute-list 10 in
!
router rip
version 2
redistribute ospf 10 metric 5
network 172.16.0.0
network 172.30.0.0
no auto-summary
Remote Location 1:
router rip
version 2
network 172.16.0.0
no auto-summary
Remote Location 2 :
router rip
version 2
network 172.30.0.0
no auto-summary
this was working config, but now its giving problem all of a sudden, which i couldn't get the reason.

Please tell us which one is working IPSEC or GRE vpn?
If IPSec is not working then you have to make clear, which type of this vpn, gre over ipsec or simple ipsec. If it is simple IPSec then your routing updates are not reaching the across the tunnel. you have two options:
1) Static routes
2) implement GRE over IPsec
