It should say:

     typedef route-distinguisher {
       type string {
         pattern
           '(0:(6553[0-5]|655[0-2][0-9]|65[0-4][0-9]{2}|'

=== AD Notes (Alvaro Retana) ===
The WG discussed this report: https://mailarchive.ietf.org/arch/msg/rtgwg/o536w2kGqGO-PULTSNTfxyO96ZQ/

There is agreement that the report is correct, but the document needs to be updated.

Also, a similar error in the string related to the route-origin needs to also be corrected.
