how many ip addresses do you have ? ----- Original Message ---- From: Daniel STICKNEY <dstickney@optilian.com> To: nanog@nanog.org Sent: Thu, April 7, 2011 10:27:01 AM Subject: Implementations/suggestions for Multihoming IPv6 for DSL sites Hello all, I'm investigating how to setup multihoming for IPv6 over two DSL lines (different ISPs), and I wanted to see if this wheel has already been invented. Has anyone already set this up or tested it ? In my research into the proposed solutions I came across this document "IEEE Communications Surveys - 2nd Quarter 2006, Volume 8, No. 2" (http://www.shim6.org/path-to-mh.pdf) which seems quite thorough. It compares routing methods, middle-box methods, and host-centric methods. It mentions "During the last years, the IETF has made several explicit or implicit architectural decisions regarding IPv6 multihoming. The main decision is to go down the path of developing the host-centric approaches" as well as "Host-centric multihoming, the approach promoted by the IETF for IPv6 multihoming, [...]". After the comparison of all host-centric methods it adds " [...], the IETF has decided by the end of 2004 to foster the SHIM approach." This approach looks interesting to me after all the comparisons, though I'm less familiar with it. I'm interested to hear your real-world experiences on this topic. Thanks, Daniel
