Re: [j-nsp] Update on 10.4R9 stability for MX?
On Thursday, May 10, 2012 01:59:55 AM Richard A Steenbergen There is a serious issue with MPLS RSVP auto-bandwidth in 10.4R9, which can cause the reservation calculations to be off by quite a bit. The least broken code we've found so far is 10.4S9, I'm surprised they haven't done an R10 yet. As far back as I can remember, Richard, you've pretty much had this particular issue with almost every major train Juniper have released :-).

As far back as I can remember, Richard, you've pretty much had this particular issue with almost every major train Juniper have released :-). I wish it was a single issue, at least then I would have one definite thing to bitch about. It's more like a dozen different issues affecting the same subsystem, in a dozen different versions of code, over the last couple of years. You could say the same thing about SNMP, it's been broken about as many times over about as many different revisions (including recent ones :/). 10.4S9 does seem to have solved this latest issue, which was causing wildly inaccurate reservations. It's almost comical when RSVP tries to reserve a several petabit LSP (not much to do with recent JUNOS except laugh at this point, right? :P), but it's a lot less funny when nearly empty high-priority LSPs get mis-calculated to several gigabits and start causing incorrect preemptions... -- 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
Re: [j-nsp] Update on 10.4R9 stability for MX?
The answer is pretty much the same with every code version. You can query the list for what others think are relevant bugs, but it's largely subjective. Depends on the size of your network, the services you use and where you're upgrading from. If you're already in the 10.4 train upgrading to a new release is (some list members may differ) supposed to provide bug fixes only and no new features or bugs. If you are coming from a much older code you may see new bugs that weren't there before as well as changes in features or syntax. Generally, speaking I haven't come across many bugs in 10.4 although we're running an older release. According to their software lifecycle policy there shouldn't be any bugs in 10.4R9 that aren't in earlier versions of 10.4. As I said earlier though YMMV considerably. 2012/5/9 Clarke Morledge chm...@wm.edu It has been a couple of months since the JTAC recommended Junos software versions has been updated for the MX. As of February, the recommendation was to use 10.4R8.5 for the MX, except that there is an issue related to BFD configurations on the DPC line cards. Supposedly, the fix is in 10.4R9. In looking at the release notes, there are some issues that have been resolved in the 11.x series but nothing noted yet for any future 10.4.x releases. Perhaps there are future 10.4.x versions planned to carry forward these fixes? I am curious to know about anyone's experience with 10.4R9 over the past few months. I have DPC only currently; i.e. no MPC hardware -- and no MultiServices. Thanks.

Haven't seen this, but to be honest, haven't paid very close attention to it :) I was told that R10 should be available early May, possibly even this week... --Daniel. ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp

We've started to implement 10.4R9 in Prod. A few MX960s with MPC DPC mix and MX80s have been upgraded without a problem (knock on wood!). We use L2VPN VPLS with OSPF/LDP/BGP.
