Guys, I have added an EBGP peer to the R3 router and advertising 4.4.4.4 via
eBGP.
The next hop I get on R3 for 4.4.4.4 is that of the ethernet on R4.
So I set the next-hop-self on the R3 to R1 link and that sets the next-hop
to the R3 ethernet link to R1.
So does the next hop-self command only work on iBGP peers when the route is
learned from eBGP?
???? im am a little confused?

Subject: BGP next-hop-self on a Route Reflector
Good morning all,
RR

I have the following above, and I am I am learning the 1.1.1.1 network via
iBGP on R1 from R3 and this is being reflected to R2, but the R2 router is
not putting this into it's routing table because the next hop in the BGP
table is unreachable.
So I tried to put on bgp next-hop-self on the RR (R1) to the neighbor for R2
but this has no affect.
I have never use RR before with the next-hop-self and assume now that this
does not would and I will have to use another method of setting the next hop
when the route reflects from R1 to R2.
Can one of you techies, please let me know if this is fact, that
next-hop-self is a no go on RRs?
Many thx indeed,
Ken
