[isp-bgp] Data Forwarding

[Tulip Rasputin <tulip_rasputin@...>]

Hello,

I have 2 routers (say A and B) at the edge of my network talking EBGP with other Autonomous system
routers, and who are in turn connected via an intermediate non BGP speaking router (say C). This
configuration is possible as i may have IBGP routers connected multiple hops away.

Say A learns 10.0.0.0/8 from its EBGP peer. It advertises this to B via IBGP. My doubt is that how
will the traffic coming at B destined for 10.0.0.0/8 reach A, when C has no knowledge of
10.0.0.0/8? The reason why i am saying that C has no knowledge of 10.0.0.0/8 is because we have
not redistributed BGP into IGP (which has over the time been proven harmful) and we are not
running IBGP on C. 

I suggested putting a default route on C, but my customer is not ready for that.

Any clues/suggestions to make this thing work?

Regards,
Rasputin
