For some definition work "works just fine", where "works" equals "doesn't work" perhaps. :) I haven't been able to successfully ISSU an MX/DPC for over 2 years, and Juniper has all but given up trying to fix it. But GRES+NSR is typically going to be a much better idea than GRES+GR. GR is actually pretty darn flawed in its design, as it assumes that all failures are graceful, even the non-graceful ones. If you don't want to blackhole a lot of traffic, NSR is a MUCH better alternative. Of course I have yet to encounter an RE failure in the wild where GRES+anything actually saves the day, but doing a hitless NSR switchover has been surprisingly helpful as a way to kick the box in response to a large number of random/obnoxious bugs, without actually having to disrupt forwarding. -- 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
