Hey! I also think that the VC is quite reliable. However, by design, it is a bit fragile. rpd can die and take the whole VC down. I also remember quite a few problems with upgrades but this is quite ancient, so maybe this doesn't apply any more.
I didn't test much, but even on the EX3300 with 15.5, you seem to have MC-LAG support (and no warnings from the CLI when using it). Dunno if this is recent or not. -- Don't just echo the code with comments - make every comment count. - The Elements of Programming Style (Kernighan & Plauger) ――――――― Original Message ――――――― From: Raphael Mazelier <r...@futomaki.net> Sent: 22 décembre 2016 18:32 +0100 Subject: Re: [j-nsp] MC-LAG reliability To: juniper-nsp@puck.nether.net > Hey, > > My experience with VirtualChassis with a lot of them (you know where) > is globally positive.
