Failover configuration_ospf to static

[niladri4u]

Static is configured for all subnets between DC and DR point to point link.from DC router service provider mpls is connected,all branch office traffic comes via Mpls ,this routing is over ospf,SP router is connected to our DC router through an L2 switch,ospf process is configured in both routers,now DC and DR point to point link is also terminated to DC router.DR is also having an Mpls link in same way.Now we need to configure backup of DC mpls (used for Br office traffic) via DR Mpls ,so that in case of failure of DC Mpls link br office traffic will take DR Mpls and then point to point link to reach DC servers .

configuration is given below

For Mpls at DC router (Routing takes effect in case of communication with branch office)
========================================================================================

router ospf 40
log-adjacency-changes
redistribute static metric 19 subnets
  redistribute ospf 30 subnets
network 172.20.10.240 0.0.0.7 area 10
maximum-paths 1
default-information originate
distance ospf external 200

Traffic via p2p link
=======================

ip route 10.50.0.0 255.255.255.0 172.16.15.84(p2p next hop) 240 (metric) name BR-OFF-BACKUP

10.50.0.0/24 use to reach DC via Mpls,I have configured static with higher metric via p2p

For Mpls at DR router
==========================================

router ospf 1
router-id 172.20.10.71
log-adjacency-changes
redistribute static metric 10000 metric-type 1 subnets
redistribute ospf 2 subnets route-map ospf2-to-ospf1
  network 172.20.10.24 0.0.0.7 area 10
distance ospf external 254

Traffic via p2p link

=========================

ip route 172.19.0.0 255.255.255.0 172.16.15.81 (p2p next hop) 240 (metric) name DC-LAN

172.19.0.0/24 (DC-LAN) is accessible from DR via Mpls ,configured static with higher metric so that in case of DC Mpls failure DC-LAN can reach via p2p.

Will it work ?

Can automatic failover be achieved or I need to configure IP SLA?

I would suggest to use IPSLA with track.

Will tracking work with ospf?

Please note  primary link for all remote office routes are via ospf,whereas backup will be via static through DR and again via ospf to store.

Would be helpful if you can provide a simple network diagram.
