Hello,

either one will work, it depends on what the requirement is. I think Cisco prefers not to redistribute BGP into the IGP, so the next-hop-self on R2 probably is the better option.

Regards,

Georg

 Hi, all
IF R3 know ebgp(bb1) next-hop-self via igp(rip),
does r2 need to next-hop-self for r3?

197.68.22.0---BB1--------R2----------R3
EBGP IBGP
1.
R3# sh ip bgp
*> i197.68.22.0 150.100.1.254(BB1) 0 100 0 254 253 i

R3#sh ip ro rip 150.100.1.0
R 150.100.1.0 [120/1] via R2, 00:00:26, Serial0/0(R2)

2. r2 next-hop-self
R3# sh ip bgp
*> i197.68.22.0 2.2.2.2(R2) 0 100 0 254 253 i
