Hi have a quick quesiton I have 2 routes on a customer site one is primary and one is backup. They are running rip and I'm running OSPF. What I was looking to do is having all the RIP updates from the customer come over the primary link and if that goes away then the secondary will take over. I was going to control that via redistribution or is there a better way? My config are:
router rip
version 2
redistribute ospf 1 metric 10 route-map redis-to-Napa
passive-interface Serial0/0
passive-interface BRI0/0
network 172.16.0.0
distribute-list prefix plist-to-Napa out
distribute-list prefix plist-from-Napa in
distance 75
no auto-summary
router rip
version 2
redistribute ospf 1 metric 5 route-map redis-to-Napa
passive-interface Serial0/0.100
network 172.16.0.0
distribute-list prefix plist-to-Napa out
distribute-list prefix plist-from-Napa in
distance 75
no auto-summary

Hi there,
It's fine the way you are doing it. One caveat, watch out for the hop count as you are bringing external RIP routes with Metric 10. Once the Metric becomes 16, the route is invalid. Not sure how many hops you have to other RIP routers from this router.

Warren,
With redistribution from OSPF -> RIP you would be able to influence how your customer would route traffic to you. Also, factor what Edison said about the route becoming unreachable when the hop count becomes 16.
Your configuration doesn't show how the traffic from your network goes to the customer. You can do that several different ways.
1. When you redistribute RIP into OSPF you can set the metric to be preferred for the route that's advertised out of the primary router.
2. You can use an offset list under RIP for routes learned from the customer and set the metric preferred for the primary route.

Hi Sundar and Edison
Thank you guys for your input really helps, I wasn't sure if what I was doing was correct till you guys verfied it. As far as my traffic going back to them. Under my ospf statement Ihave the following:
router ospf 1
router-id 172.19.105.6
log-adjacency-changes
redistribute connected subnets route-map redis-connected
redistribute rip metric 10 subnets route-map redis-from-Napa
network 172.19.25.60 0.0.0.3 area 1
