Abstract Abstract
The current route target distribution specification as described in The current route target distribution specification as described in
[RFC 4684] defines Route Target NLRIs of maximum length of 12 bytes. [RFC 4684] defines Route Target NLRIs of maximum length of 12 bytes.
The IPv6 specific Route Target extended community is defined in [RFC The IPv6 specific Route Target extended community is defined in [RFC
5701] as length of 20 bytes. Since the current specification only 5701] as length of 20 bytes. Since the current specification only
supports prefixes of maximum length of 12 bytes, the lack of an IPv6 supports prefixes of maximum length of 12 bytes, the lack of an IPv6
specific Route Target reachability information may be a problem when specific Route Target reachability information may be a problem when
an operator wants to use this application in a pure IPv6 environment. an operator wants to use this application in a pure IPv6 environment.
