Re: IS-IS and IPv6 LLA next-hop - just Arista, or everyone?

hey,

I did an L3VPN over SRv6 test recently using IS-IS as the IGP. I thought it was quite cool that I didn't configure any IPv6 addressing at all in the core... simply enabled v6 on interfaces and allowed FE80 LL's to run... IS-IS neighbored up... then added a mp-ibgp v6 loopback (rfc 4193) to the PE's and let BGP neighbor up... L3VPN worked over SRv6 (of course with all that weird (new) locator magic).

For less adventurous - you can also do unnumbered ISIS or OSPF. It works equally as good and enables one to do plug-and-play SR-MPLS like you would do layer-2 network. -- tarko
