Opened: Jun 25, 2018

Severity: 3-Major

Symptoms

TMM may change the source port of Routing Information Protocol (RIP) packets sent by ripd to something other than port 520. Neighbor routers will not accept these packets and RIP routing will not work. If the TMM instance handling the outgoing packet would not be selected to handle return traffic by the hashing algorithm in use, the source port of the traffic will be modified so the hashing algorithm returns the same TMM instance.

Impact

Dynamic routing using RIP does not work if the traffic hash of the packets does not match the TMM handling the outgoing traffic.

Conditions

-- Multiple TMM instances. -- RIP routing configured. -- After reboot.

Workaround

Delete the sys connection for RIP; the new connection is expected to use the correct port.

Fix Information

None
