[j-nsp] OSPF external routes

[Olivier Benghozi]

You're redistributing eBGP to OSPF.

Received OSPF routes from the other ASBR will be inserted in the RIB with preference 150.
Received eBGP routes will be inserted in the RIB with preference 170.

So OSPF will always be preferred over BGP routes unless you change the preference via an import policy.

 I guess you obtain a funny, non deterministic solution (first running BGP session wins).


But you don't really want to redistribute BGP to OSPF. Your architecture probably lacks an iBGP session between both ASBR. Then you'll only deal with BGP routes.
