Not quite, but thanks for your answer anyway.
What I was looking for was that I was in the beginning kind of blinded by
the fact that they were running different routing protocols. The fact is
that if two routers are connected to the same LAN but router A runs RIPv2
and router C runs BGP, router A can still sent to router C if (1) there's a
static route to router C on router A, or if a third router B running both
RIPv2 and BGP are located on the same LAN as A and C, and A thereby learns
about C from B.
(use a fixed font for best view)
[RouterA]-----\
(RIPv2) |
|---<Network1>---[RouterC]---<Network2>
| (BGP)
[RouterB]-----/
(RIPv2+BGP)
1) RouterB learns about Network2 from RouterC's BGP info.
2) RouterA learns that RouterC is the best path to Network2
from RouterB's RIPv2 info.
3) RouterA can now send to Network2 via RouterC regardless
of what routing protocols they're using.
Are you confused, well wait until you watch the next episode of Cisco Soap.

Hi Drew,
I have just had a word with Jeff (read this chapter) and what I understand
is
that although it does not say it, there is definatley redistribution going
on
here. When they mention the tag field, this shows that the route was tagged
"when redistributed". Therefore they are all going to know about all
networks.
Is this what you were after, I did I completeley misread your question?????
