Abstract

The base IETF TRILL (Transparent Interconnection of Lots of Links) protocol has a TRILL campus-wide MTU feature, specified in RFCs 6325 and 7177, that assures that link-state changes can be successfully flooded throughout the campus while being able to take advantage of a campus-wide capability to support jumbo packets. This document specifies recommended updates to that MTU feature to take advantage, for appropriate link-local packets, of link-local MTUs that exceed the TRILL campus MTU. In addition, it specifies an efficient algorithm for local MTU testing. This document updates RFCs 6325, 7177, and 7780.
