BESS Working Group The goal of this draft is to go over the technical aspects of SRv6 Inter Domain routing in the context of IP VPN and EVPN overlays and seamlessly stitching the overlays across inter domain boundaries. This draft goes over the SRv6 Design and Operational technical caveats regarding SRv6 Inter Domain routing in detail. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.

Terminolgoy used in defining the SRv6 Inter Domain Routing specification. IDR: Inter Domain Routing

There are not any IANA considerations.

No new extensions are defined in this document. As such, no new security issues are raised beyond those that already exist in BGP-4 and use of MP-BGP for IPv6. The security features of BGP and corresponding security policy defined in the ISP domain are applicable. For the inter-AS distribution of IPv6 prefixes according to case (a) of Section 4 of this document, no new security issues are raised beyond those that already exist in the use of eBGP for IPv6 .

Many thanks to Ketan Talaulikar, Robert Raszuk, Igor Malyushkin, Linda Dunbar, Huaimo Chen, Dikshit Saumya for your thoughtful reviews and comments.
