  1. Multilevel TRILL-IS-IS Radia Perlman Radia.perlman@intel.com

  2. What might stop scaling? • 16-bit nickname • MAC learning table • Broadcast traffic • IS-IS computation

  3. Multilevel IS-IS • IS-IS has the capability of multilevels • What issues might TRILL introduce? • nicknames

  4. Nicknames • Must be unique • R1 only sees LSPs at R1’s level • So • Need to allocate a piece of nickname space for each area (including level 2 “area”) • Need to make sure Rbridges in an area know which nicknames they can choose • Need to make sure Rbridges can route to foreign nicknames

  5. Some ideas • Have highest priority border Rbridge R1 advertise area’s nickname range within area • But, this would be incompatible • So…have R1 claim ownership of all nicknames not allowed in the area • Also, have R1 advertise, in layer 2, the reachable nicknames in its area
