Redistributing bgp to ospf

[massimo.disanto]

Hello all,

I'm having a problem after configured redistributing bgp to ospf on CE router.

My customer claimed that yesterday for 10 minutes his routing cleared when CE sent new network advertisement on his LAN ( there is a FW Cisco asa and a l3 bridge ).

What Can cause this 10 min downtime???

Kind regards

Massimo

Hi,

I would be careful about redistributing BGP routes to OSPF as you could overwhelm the OSPF routers with all the routes.

Are you redistibuting all BGP routes into OSPF or just some of them?

Hello Borgenstrand,

thanks a lot for your feedback, i was suspecting something like that.

I'm not responsible for the config, i only have reading privilege.

Could you suggest me some command i can do, to analyze which BGP routes are being redistributed via OSPF?

Thanks again

To find what BGP routes have been redistributed into OSPF you might use the show ip ospf data external command.
