Howdy,

I am using a multi-vendor network and validating the inter-operability.

When I announce a default route to a BGP peer using default-originate applied to the peer group/neighbor configuration:

in vendor A that route is sent with ORIGIN 0 (internal)

in vendor B that route is sent with ORIGIN 2 (Unknown)

Downstream it looks like this:

Network Next Hop Metric LocPrf Weight Path

* i 0.0.0.0 192.168.27.1 100 0 ?

*>i 192.168.25.1 0 100 0 i

* i 192.168.27.2 100 0 ?

I don’t believe that it has a functionality impact but I would like to know which one you think follows the RFC more closely.

thanks,

-Drew
