Description (partial)

External router is connected to border leafs of ACI fabric over L3/SVI interface. Border leafs forward the traffic going outside of fabric to this external router.  If router mac is changed on external router for this L3/SVI interface, then traffic going out is disrupted on external  router until new router mac gets updated on border leafs. Traffic disruption could be up to 15 minutes.

This happens when router mac is changed on external router connecting to border leafs of the fabric.
