Really? It seems like control plane memory is absurdly cheap and plentiful these days. I can't even think of any situation outside of a memory leak in which I've run low on memory on a well maintained modern router (i.e. not dusting off an old 7507 in 2009) in the last 10 years. Modern Juniper RE's have all been shipping for 4GB for a few years now (with more to come soon, no doubt), while last I heard rpd can't even address more than 2GB currently. It doesn't seem like I or anyone else with a reasonable router config (not counting massive route-server apps which would be better served by JCS anyways) are in any danger of running out any time soon. Meanwhile, my RE's are constrained at 100% CPU every single time there is any instability or reconvergence event in the network (or sometimes they're at 100% cpu 24/7 depending on how many unresolved rpd bugs I'm being affected by at any given moment :P). Given those realities, I'd gladly trade memory for better performance any day of the week. -- Richard A Steenbergen <[email protected]> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
