Here's a start! "Support for OSPFv3 and IS-IS is various beta states currently; IS-IS for IPv4 is believed to be usable while OSPFv3 and IS-IS for IPv6 have known issues." On Nov 10, 2016 6:50 PM, "Tim Jackson" <jackson.tim () gmail com> wrote:
Maybe you didn't look hard enough? ISIS feature support in a bunch of different products has sucked for a long time vs OSPF, but that's a pretty well known and accepted fact. Generally these features are the same across multiple products from the same vendor (usually across the same OS anyway)... Just name 1 feature that was in Cisco and wasn't in other implementations........... Just one.. Something.. Does ISIS on IOS make and hand out ice cream on Fridays? I want to know if I'm missing out.. -- Tim On Thu, Nov 10, 2016 at 6:33 PM, Josh Reynolds <josh () kyneticwifi com> wrote:My first post said the following: "Vendor support for IS-IS is quite limited - many options for OSPF."

As far as all the documentation I have read, and some of the documentation you linked to, it works just fine on quite a few vendors, and a few people on this list. Your original point mentions nothing about wider OSPF adoption, which you seem to have shifted to to deflect having to provide any actual details. Are we to assume that your original point was incorrect? As far as the landscape as a whole, I have seen quite a few networks that get by with either protocol just fine, the use-case for a given network is not such a broad landscape, so I think "use the right tool for the job" seems very apt, and that you can't just say that only two protocols are suitable for all jobs. /Charles On Thu, Nov 10, 2016 at 6:00 PM, Josh Reynolds <josh () kyneticwifi com> wrote:As cute as your impotent white knighting of one vendor is (I very muchlikeJuniper BTW), you're absolutely ignoring my original premise and point because you got your panties in a wad over a potential triviality ofaninternet comment - where documentation exists, should one take thetimetogo through it, to find discrepancies between them. So, if you'd like to prove your point and earn brownie points with$vendor,on a feature by feature basis please take the time to consultdocumentationof two vendors products (you can even pick the platform and subversion release!) to refute my claim. This has nothing at all to do with thepointof my statement mind you, it's simply a sidetrack that has wastedenoughtime already. That said, glance across the landscape as a whole of all of theroutingplatforms out there. Hardware AND softwsre. Which ones support barebonesIS-IS? Which ones have a decent subset of extensions? Are theycomparableor compatible with others? The end result is a *very mixed bag*, withfarmore not supporting IS-IS at all, or only supporting the bare minimumtoeven go by that name in a datasheet. Thus, my point stands. If you want as much flexibility in yourenvironmentas you can have, you want OSPF or BGP as your IGP.
