In our experience w/J-series running the old/regular JUNOS (can't speak to JUNOS-ES, which is really more of an integration of security features to make J-series a mini-SRX), this would probably be a bad idea (I'm assuming you mean more than 4000 routes, since you mention 400k later in the email). We evaluated J-series for use as route reflectors, and found that they suffer GREATLY from the ye olde slow rib/fib installation bug. What might take a few minutes to install under extraordinary conditions like coming up from a fresh restart on M/T/MX could take 30 minutes to in some cases HOURS to install on J-series. When I asked Juniper people about it, they basically said "we don't really support/recommend J-series for this application, and the software is heavily optimized towards providing packet forwarding performance at the expense of bgp performance". Of course they said that AFTER we spent money on those stupid route reflector software licenses, which they continue to sell even though the box is completely unusable as a route reflector. :) YMMV but on J-series running JUNOS as of 9.3R4 the only words I can use to describe loading up a lot of bgp routes/neighbors is "epic disaster". Maybe JUNOS-ES is better or different or something, I dunno. -- Richard A Steenbergen <r...@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
