BCP-006 IPv6 Peering

Last updated: 8 July, 2011

Status: Current

IPv6 peering at the Ottawa Internet Exhcange has been in place at least between the route servers and participating peers for a number of years. Over the course of time features such as IPv6 auto-configuration and router advertisement protocol [RFC4861].

Any IPv6 peering participant must disable auto-configuration on every interface that participates in the OttIX peering LAN. Also, the IPv6 router advertisement protocol must be disabled. IPv6 addresses are allocated from a /48 dedicated network using a prefix length of /64, statically. OttIX uses /64 addressing in order to keep EUI-64 and CGA (Cryptographically Generated Addresses) [RFC3972]. There is nothing at this IX that requires the use of dynamic addressing.

Also, it is important for the IXP peering operator to ensure that the MTU size of IPv6 packets is set at no less than 1280 bytes [RFC2460].

Peering is available at both OttIX route servers and should OttIX peers wish, directly with each other.
