Hi Steven,
It goes a little something like this...
R1------R2------R3------R4
AS100 AS100 AS200 AS200
Without next hop self, R4 will see routes coming from AS100 with a next hop
address of the interface of R2. This can be a problem if R4 does not know
how to get there. On R3 if you put a next-hop-self after the neighbour
statement for R4, R4 will get AS100 routes with R3 as the next hop and hence
know how to get there.
I think that's right anyway.
Regards,
Lachlan

Subject: next hop self...
I know this is a silly question but I am having a hard time
understanding the function of the next hop self command. I read up on it
in Halabi and I'm still having problems. Anyone care to shed some light?
Thanks,
Steve
