[j-nsp] Next hop self for BGP

[David water]

Hi All,

I guess there are multiple way of changing next-hop attribute to self. One
write import policy with next-hop-self and apply under EBGP group, other is
write export policy under IBGP group and other is at neighbor level.
Anything else? Can some one describe it when and which one to use? In JNCIP
book, it is as import under the IBGP group, I am still confuse what exactly
are we doing there to avoid suboptimal routing via RR?
