Hi everyone,
I'm currently struggling with getting the NITB example
(https://osmocom.org/projects/cellular-infrastructure/wiki/Osmocom_Network_In_The_Box)
running.
My problem looks as follows: I do see messages reaching the HNBGW
component but whenever the HNBGW tries to reach the SGSN component I get
the following error:
DLSS7 <000c> osmo_ss7_hmrt.c:278 m3ua_hmdc_rx_from_l2(): dpc=188=0.23.4
not local, message is for routing
DLSS7 <000c> osmo_ss7_hmrt.c:258 MTP-TRANSFER.req for DPC 188: no route!
Using the VTY interface I can see that only HNBGW and MSC annouced their
code points towards STP. :
as-rkm-1 AS_ACTIVE 1 0.23.5
as-rkm-2 AS_ACTIVE 2 0.23.1
However, I can not see the code point 0.23.4 (SGSN). In addition, I'm
also not sure if the routes are valid as they are:
7.255.7 0 as-rkm-1 ? ? ?
7.255.7 0 as-rkm-2 ? ? ?
Here are my configurations (without the logging parts):
