i am doing BGP with 2 diffrent service providers with internet links terminated on 2 diffrent routers.i will accept only default route from both the service providers.now both the internet routers are connected to 2 diffrent L3 switches with Each router connected to both L3 switches.Behind the L3 switch is the Public IP pool which will be actually announced in BGP with service provider.Between Internet router and L3 switch i am running ospf.
I will redistribute the default route from BGP into ospf and Ospf will be redistributed into BGP so that internal Public IP pool will be reachable to Internet router and would be able to announce the same.
now instead of redistributing BGP into ospf i am configure default-information originate metric 1 under ospf will my purpose will be served ?? i want that both the L3 switches should get the default route towards Internet routers.
secondaly if i just redistribute ospf 100 (Processs) under BGP,will my internet router will get the public ip pool.
