Unless the question specified that you needed to make sure the origin is know then it wouldn't be application. Stating that it originated in AS 200 is only referencing the BGP component not whether it originated in EGP, IGP, or unknown.

I wrote an as-path list applied a filter list to the neighbor (bb2) and when I do a show ip bgp, I do see all of the routes from that as follows: *> 10.1.100.0/24 10.2.6.2 0 0 200 ? *> 10.1.101.0/24 10.2.6.2 0 0 200 ? *> 10.1.108.0/24 10.2.6.2 0 0 200 ? *> 10.1.109.0/24 10.2.6.2 0 0 200 ? *> 10.5.100.0/24 10.2.6.2 0 0 200 ? *> 10.5.101.0/24 10.2.6.2 0 0 200 ? *> 10.5.108.0/24 10.2.6.2 0 0 200 ? *> 10.5.109.0/24 10.2.6.2 0 0 200 ? Common sense tells me I have met the requirements, but the origin on these routes is incomplete, which means that technically they did not originate in AS200. Am I reading too far into this, or do I actually have the problem correct? Thanks
