Abstract:
A system and method are disclosed for enabling interoperability between asymmetric and symmetric Integrated Routing and Bridging (IRB) modes. A system is configured to receive a route advertisement, examine the label fields of the route advertisement, and determine whether Layer 2 or Layer 3 information is conveyed. The system is further configured to build a route advertisement to advertise to a second device based on whether Layer 2 or Layer 3 information is conveyed in the first route advertisement.
