While this is GROW question ... perhaps it would be very helpful to get
some more real data on what type of routers customers of the IX use to peer
within IX ? Why such equipment is considered at best as 2nd class citizen ?

For my BB IX peerings I would in fact put the best routers to peer outside
of my network on the edge - not just some junk or homebrew bgp/igp.

It is anyway interesting that now fear of IGP bugs is used a motivation for
BGP protocol extension.

My personal problem with proposed RS SAFI is that it delays even further
both RS support and IX operators support for ability to send multiple paths
to me as client of the IX. And I need those multiple paths for already
stated reasons.

One would hope that we learn something from years of PIC experience ...

Regards,
Robert.
