Gentlemen,

Thanks for the input. I too thought of injecting a default route, however
according to the directions that does not satisfy the requirements of the
lab. I am going to speak to the person who created this lab. Once I find
the answer I will let you all know. Perhaps he misstated something. It seems
from our discussions that there is only two ways of getting specific routes
into BGP (i.e. non default routes). That is via the network command or to
redistribute.

Actually, I am betting that he meant that I couldn't use network or
redistribute commands on the router that physically connects to the
backbone. If that is true, then I will run one network command for a
specific subnet of 135.3.0.0 /16 on one of the other routers. Then I will
then aggregate that route out to the backbone.

I'll let you all know, and thanks for the input

I could be wrong. but how about...

neighbor x.y.z.a remote-as <<backbone as>>
neighbor x.y.z.a default-originate

This *could* be a third way of injecting the *route*. Of course this will
inject a default route, but it is one method that satisfies both of your
criteria (ie. dont use network or redistribute, dont use static, no other
ibgp/ebgp peers should know about this route)

What do you think ?
