Opened: Sep 18, 2019
Severity: 3-Major

Symptoms

The IPv6 Management route has lower metrics than the static IPv6 tmm route. As a result, traffic that matches the default route goes to the management interface.

Impact

The incorrect routing table sends the traffic that matches the default route to the management interface.

Conditions

-- Create an IPv6 management route, which is going to be a default gateway. -- Receive another default gateway from a configured peer using any of dynamic routing protocols (BGP, OSPF, etc.)

Workaround

None.

Fix Information

IPv6 routes now prioritize TMM interfaces.
