​Since clients will likely eBGP peer to both route servers and send pretty
much the same UPDATES to both you do not need any session between RSes to
choose best one one and second best on the other towards the clients :) In
fact in RS case tie break may be rtr_id :)  Very easy to set such
preference in cli.

All,

And just for the record here the idea for NH SAFI has been proposed by Ilya
& myself in 2012 ...

Best,
