BGP Quick Clarification Question

Unanswered Question
Jan 6th, 2009

Greetings,

Router BGP is redistributing an OSPF instance. The OSPF instance carries a 10.10.10.x/24 and 192.168.10.x/24 networks. Do I need to specify both networks in bgp? For Example

router bgp 65000

network 10.10.10..0 mask 255.255.254.0

network 192.168.10.0 mask 255.255.255.255

redistribute ospf 100

Thanks

I have this problem too.

No you don't need to have network statements if these are in the IGP routing table and you are redistributing OSPF into BGP.

The network statements would be needed if they were in the IGP table but you were not redistributing into BGP.

Edit - you may also want to look at this doc as there are a number of options as to which types of OSPF route you redistribute into BGP -
