Fixed In:
14.1.0

Opened: Feb 15, 2017

Severity: 3-Major

Symptoms

In diameter message routing framework, in the profile session config, there is no keyword in the 'origin-host-rewrite' option that allows for modification of this field based on the egressing tmm on the server-side connection of the LTM. If this profile is applied to a diameter peer config that has a connection-mode of 'per-tmm', this does not follow the recommendations of RFC6733. With this config, each tmm on the LTM device maintains it own connection to the diameter server on the server-side, and therefore needs its own DiameterIdentity.

Impact

Violates RFC 6733 in default installations of LTM.

Conditions

If 'per-tmm' connection-mode is specified.

Workaround

Use an iRule to have a separate Diameter identity for each connection.

Fix Information

The system now provides unique diameter identities from configuration objects.
