Well, that all depends what you want to do with the BGP routes. The EX has more than enough CPU and RAM to take a full table or two and do something useful with it, you just can't install more than 12k unicast routes into TCAM for hardware forwarding. Of course since Juniper has a policy-statement option sitting between the RIB to FIB export, you could very easily export a limited number of routes to hw (i.e. default routes) while still handling full BGP at a protocol level. Or at least you could, if this functionality wasn't crippled in software. Even though the small EX's have 1GB of DRAM, there is a rlimit on rpd memory somewhere around 80MB which causes it to coredump if you use too much memory. I can't quite tell if this is just someone being silly (assuming you'll never need more ram with only 12k routes), or if this is being done intentionally to cripple the product so it can't be used as a route reflector (*) (even after you buy a BGP license). Either way it's a horrible disservice to the product, since this could be used to solve the classic "how to support full bgp on a top-of-rack L3 aggregation switch" problem without resorting to ghetto Cogentesque 2 BGP session hackery. If you think this would be useful, please ask Juniper to remove the crippling rlimit and let the device handle full routes. (*) On the subject of route reflectors, has anybody else noticed that even though they fixed the long standing slow FIB install bug in most platforms around JUNOS 8.5, it is still happening on J-series boxes? We were trying to use them as RR's, but found this old bug still alive and well, ironically on the platform that doesn't actually have a hardware FIB to install to. Also to be filed under Irony, the O-series has no such problem, and makes a very snappy route reflector. :) -- 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
