Description

In EVPN-MPLS active-active scenario management access to the device behind Mx for Ex was intermittently breaking.

Symptoms


EXVC looses management connectivity intermittently which is connected to Mx on fpc1 on both sides of Mx in an EVPN-MPLS active-active setup.
When the ping is initiated from the mx1 to exvc we are not seeing the packet reaching the DF back but the ping to BDF is working fine.
ExVc was upgraded to the latest version which solved the issue.
