“…Other methods are possible: for example, the specification in this document and the specification in [RFC7782] could be simultaneously deployed for different AAE groups in the same campus. If the method defined in [RFC7782] is used, edge TRILL switches need to support the capability indicated by the Capability Flags APPsub-TLV as specified in Section 4.2 of [RFC7782]. If the method defined in this document is adopted, all TRILL switches need to support the Affinity sub-TLV defined in [RFC7176] and [RFC7783].…”
