A small addendum: The use of D-PATH Domain IDs for loop detection purposes are split in the document. Section 4.d which defines D-PATH mentions two properties: 1. When a looped entry, having been received, may be considered for use even when it is looped. 2. It MUST NOT be exported. In traditional BGP-speak, it MAY be eligible circumstantially for selection in the LocRib, but is ineligible for placement into the AdjRibsOut. Section 6 covers the changes to route selection when D-PATH is present for the different forms of ISF routes. This parallels BGP's route selection text in RFC 4271, Section 9.1.2. However, BGP's section discusses the AS loops as part of that section. I'd recommend that a portion of the text relating to route selection and loops be placed in the ipvpn document's section 6. Having all of the rules in a single place will likely avoid certain classes of implementation bugs and will ease in citation of the rules for the future. -- Jeff _______________________________________________ BESS mailing list BESS@ietf.org https://www.ietf.org/mailman/listinfo/bess
