LB for SMPP / SMSCs in NFV environment
Hi all, We are trying to use the LMT F5 (installed on Openstack) to be SMSC Getaway (Short Message Service Center – Getaway) for external messages Our installation is based on minimum 2 SMSCs, and Maximum 8 SMSCs So, if an external application will connect to the SMSCs, the F5 will get the connection request (bind) and will try to connect to all active SMSCs with the same bind connection For messages running on top the active connection (submit_sm), the F5 will do a round robin between all the active SMSCs. Connection from Client & message from SMSC: 1:: Client1 ---(bind)---> F5 1-1:: F5 ----(bind)----> SMSC1 1-2:: F5 ----(bind)----> SMSC2.... (max of 8 SMSCs) 1-1':: SMSC1 -----(bind_resp1)----->F5 1-2':: SMSC2 -----(bind_resp2)----->F5.... (max of 8 SMSCs) 2:: If (bind_resp1 = OK) or (bind_resp2 = OK) or (max 8 SMSCs); respond back to Client1 with OK 2:: Else; respond back with NOK 3:: SMSC1 ----(deliver_sm1)---->F5 [store sequence, use internal sequence] 3-1:: F5 ----(deliver_sm1)---->Client1 4:: SMSC2 ----(deliver_sm2)---->F5 [store sequence, use internal sequence] 4-1:: F5 ----(deliver_sm2)---->Client1 4-1':: Client1 ----(deliver_sm_resp2)---->F5 3-1':: Client1 ----(deliver_sm_resp1)---->F5 4-1'':: F5 ----(deliver_sm_resp2)---->SMSC2 [use original sequence] 3-1'':: F5 ----(deliver_sm_resp1)---->SMSC1 [use original sequence] Connection from Client & message from Client: 1:: Client1 ---(bind)---> F5 1-1:: F5 ----(bind)----> SMSC1 1-2:: F5 ----(bind)----> SMSC2....

ADDING A SYSTEM ID TO AN SMPP VIP
I need help on adding a system id to an SMPP VIP for authentication. My topology involves an ESME, two smpp firewalls which communicate via separate F5 vip's To the SMSC. So, my topology looks like this. ESME>>>1ST F5 VIP 1ST F5 VIP forwards t0 1st smpp firewalls. 1st smpp firewalls are configured to forward to second f5 VIP. 1ST SMPP FW>>>>>2ND F5 VIP 2nd F5 VIP load balances to 2nd smpp firewalls. 2nd f5 vip>>>2nd smpp firewalls. 2nd smpp firewalls are configured to forward to third f5 vip. 2nd smpp firewalls >>>>> third f5 vip. third f5 vip load balances to SMSC. 3rd f5 vip>>>SMSC. i used the irule based on this beautful irule on this thread. https://devcentral.f5.com/questions/balancing-smpp-traffic-based-on-recipient-address. The irule used is listed in comment. The bind tranceiver message hits the 1st smpp firewall, and fails on hitting the second F5 VIP, as the second F5 VIP doesn't have the SYSTEM ID parameter configured. How do i configure the system ID on the 2nd and third F5 VIP's.ADDING A SYSTEM ID TO AN SMPP VIP
