Last updated on DECEMBER 31, 2020

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 8.4.0 and later
Information in this document applies to any platform.

Symptoms

We received a storm traffic today which should be sent to our Home Subscriber Server (HSS) through MRNSET ID=100.

There is a Mated Relay Node (MRN) set with 4 Destination Point Codes configured in a Dominant mode:
[EDITED]
RPC_HSS_PC1 (RC=10)
RPC_HSS_PC2 (RC=20)
RPC_HSS_PC3 (RC=30)
RPC_HSS_PC4 (RC=40)

It was observed that the traffic were sent to all HSS as defined on the MRNSET but it was also sent to the remote PC RPC_LAB_VSTP which is not part of the MRNSET.
