(Section 3, page 6.) So now the CMTS vendors can argue that what they're doing actually follows the spec. :p<br /><br />I'm still going to ask Cisco to at least add a toggle for accepting/rejecting hop-limit 0 packets, like some (not all) Juniper gear has.Anonymoushttps://www.blogger.com/profile/07531608367178879720noreply@blogger.comtag:blogger.com,1999:blog-7766818007736336316.post-64281645127943587282017-12-27T21:31:32.921-08:002017-12-27T21:31:32.921-08:00It's too bad you decided to go with an ASA ins...It's too bad you decided to go with an ASA instead of a 1921 or something, you could have forgone all this headache and set up a ipv6inip tunnel with Hurricane Electric - they do a whole tutorial and everything if you're interested in the service provider aspect (setting up AAAA dns records and glue records for your domain, native ipv6 reachable mail/web servers, etc.). Plus, you get a /64 for the outside and a /48 routed to you - free. It's at http://tunnelbroker.he.net if you're interested.<br />Charter haven't sorted their ipv6 offering out (hopefully they just bite the bullet and go native dual stack) so I've had to go this path. Admittedly, if *working* native dual stack were on offer, I'd be tempted to go with an ASA just to consolidate a router and a switch into one device.Anonymoushttps://www.blogger.com/profile/14532040052993296448noreply@blogger.comtag:blogger.com,1999:blog-7766818007736336316.post-1138097501202822312017-12-26T15:20:05.398-08:002017-12-26T15:20:05.398-08:00According to http://forums.xfinity.com/t5/Your-Hom...According to http://forums.xfinity.com/t5/Your-Home-Network/Stunningly-poor-IPv6-tech-support-Modem-in-Bridge-Mode-for-IPv6/td-p/2895476/page/2 the issue is Arris, but I'm still waiting for an update on the thread.Anonymoushttps://www.blogger.com/profile/07612414303963632199noreply@blogger.comtag:blogger.com,1999:blog-7766818007736336316.post-72875517625067451892017-10-12T04:32:28.023-07:002017-10-12T04:32:28.023-07:00I'm in TWC, now Spectrum, land (or, not Comcas...I'm in TWC, now Spectrum, land (or, not Comcast) and I'm seeing this as well on my SRX.

I used to receive a prefix-delegation and now since the upgrade, I am receiving the dreaded "Hop Limit 0" DHCPv6 XID Advertisement. It's easily reproducible and I got the repsonse from Tier 2 saying it should be fixed in a couple of hours. It's now into the afternoon and still getting "Hop Limit 0".
