Setup as follows
BB1 (AS254) >> EBGP >> R1 (AS100), R2 (AS100), R3 (AS100) >> EBGP >> BB2
(AS54)
AS100 = Full mesh among R1, R2, R3
There is full IGP reachbility from AS100 to AS254 and AS54.
Qns.) Is there still a need to use 'next-hop-self' on both R1 and R3 to
neighbor R2. So that R2 will learn R1 as the next hop address to reach AS254,
and R3 as the next hop address to reach AS54 prefixes?
My understanding of using 'next-hop-self' is when there is no IGP routes from
R2 to BB1 and BB2.
Did an ASET lab, solutions showed using 'next-hop-self' even R2 has IGP
routes to BB1 and BB2.
Cheers
