The IPv6 specific Route Target extended community is defined in [RFC 5701] as length of 20 bytes. Since the current specification only supports prefixes of maximum length of 12 bytes, the lack of an IPv6 specific Route Target reachability information may be a problem when an operator wants to use this application in a pure IPv6 environment. @@ -38,25 +38,25 @@ Internet-Drafts are working documents of the Internet Engineering Task Force (IETF).
