[j-nsp] JUNOS Equivalent to CISCO IOS next-hop-self

[Jeff Wheeler]

I question the utility in using next-hop-self on internal sessions, or
even eBGP import policy-statements. In my ASes, I keep the remote (/30)
next-hop and import the /30s into my IGP. This allows me to tweak the
metrics on those /30s as another means of controlling my egress paths.

When you rewrite learnt next-hops to the addresses of your own routers,
you lose the ability to influence the IGP-cost step in BGP best-path
selection based on the specific eBGP peer.

One thing I have always wished for is the ability to skip the external >
internal step in best-path selection, which comes before IGP cost. This
would have to be applied through the entire AS to avoid inconsistent
best-path decisions (routing loops), but I think it would be useful.
