Abstract:
An EVPN Inter-Domain interconnect solution is required when two or
more sites of the same Ethernet Virtual Private Network (EVPN) are
connected to different IGP domains or Autonomous Systems (AS) and
need to communicate. The Inter-Domain Option-B connectivity model is
one of the most popular solutions for this type of EVPN connectivity.
While several documents address specific aspects of this interconnect
approach, none provide a comprehensive overview of how Inter-Domain
Option-B connectivity affects EVPN procedures. This document
examines the behavior of EVPN procedures in an Inter-Domain Option-B
network and proposes solutions to the identified issues.
