Bug ID 828601: IPv6 Management route is preferred over IPv6 tmm route

Last Modified: Sep 13, 2023

Affected Product(s):
BIG-IP All(all modules)

Known Affected Versions:
14.1.0,,,,,, 14.1.2,,,,,,, 15.0.0, 15.0.1,,,,, 15.1.0,,

Fixed In:

Opened: Sep 18, 2019

Severity: 3-Major


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.


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


-- 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.)



Fix Information

IPv6 routes now prioritize TMM interfaces.
