Alan, what AS is R2 in? If R2 is in As 10, then you only need next-hop-self
to R1 ONLY if R1 does not possess a route to R3. There is no need for next
hop self to an EBGP peer as this function applies automatically.
So the rules are:
1. Next Hop Self only MAY be required for IBGP peers.
2. Next Hop Self is required when NO route exists (in the IBGP peers route
tables) to the next hop address of an advertised route (advertised route is
typically EBGP, but could be IBGP with route reflectors).

Subject: RE: BGP Next hop self
Hi all,
With only 2 weeks till me second attempt I am now in the panic mode.
Here is my question.
r1 ------- r2 ------- r3
r1 being in bgp as 10 and r3 being in bgp as 20 and r2 is the border router.
Would I use the bgp next hop self command on r2 pointing to both r1 and r3?
