Hi,
I encounter issues when I try to create multiple UPFs with stage-1.
I run 2 UPFs based on 2 “uptun” interfaces and change the SMF configuration with 2 addresses for UPFs as follow:
smf:
freeDiameter: smf.conf
pfcp:
- addr: 127.0.0.3
- addr: ::1
upf:
- addr: 192.168.1.206
- addr: 10.0.0.101
When I start SMF, it can build the PFCP connection with the first UPF. But SMF gets errors which say it is unable to build a PFCP connection with the second UPF, i.e., “WARN: [1] LOCAL No Reponse. Give up! for step 1 type 5 peer [10.0.0.101]:8805 (pfcp_xact.c:671)”. In the Wireshark, I see SMF received the “SxAssociation_Setup_Response” from all UPFs. However, SMF keeps sending “SxAssociation_Setup_Request” to the first UPF [192.168.1.206]. Meanwhile, the first UPF [192.168.1.206] shows “REMOTE Request Duplicated. Retransmit! for step 2 type 5 peer [(null)]:0 (pfcp_xact.c:438)” and an assert error “ASSERT: !(0). Unknown family(0) (unix/sockaddr.c:246)”, see attached figure.
Whether my way to create multiple UPFs is wrong or incorrect configuration?
Thanks,
Qiang
