BGP and OSPF in BayRS 13.10
Callis Goodrich
We are having some configuration problems with a Bay ASN router
configuration.
Specifically, we cannot get BGP-sourced routes injected into the OSPF
database. I have read and searched the ver. 12.20 documentation CDrom
on the OSPF and BGP chapters and configured the router accordingly,
but with no success.
A BGP accept policy was added which alllows the BGP routes to show up
in the
routing table, and the OSPF Global parameter is set for Boundary AS
router=TRUE. This particular ASN router (OS ver. 13.10) has 1
ethernet
interface running OSPF, 1 ethernet interface running BGP-4, and 1
serial ISDN
link running OSPF. The routing table shows the routes coming from BGP
and also
from OSPF, but the "bcc> show ospf lsdb" does not show any of the
BGP-sourced
routes in the OSPF database.
Do you have any suggestions on configuration items to check? Thanks
for your help and suggestions,

You just need to add an OSPF accept policy with the "route source" and
"ext route source" fields set to BGP.
I cannot find this is any Bay manual either, but I think it's covered
in the Advanced IP class.
RFC1403 defines the standard for OSPF/BGP interaction (see
http://www.faqs.org/rfcs/rfc1403.html). Section 2.2 states that
the vendor SHOULD allow the administrator to control which BGP routes
are accepted by OSPF. Bay has chosen to implement this feature.

Once intra-as-routing is disabled, you use OSPF _announce_ policies to
regulate what is announced to the OSPF LSDB.

The updated RFC is 1745 which covers OSPF/BGP-4 interaction.
Not much has changed, but its good to reference the updated RFC.
