Landslide: MME Nodal - Why emulated SGW is not answering to Create Session Request sent by real MME?
SGW and PGW emulated
Two problems has been seen in customer's trace:
Create Session Request seen in the trace corresponded to a S5 message. It meant real MME sent the S11 to a real SGW, and this node was forwarding the message to the emulated PGW, but in MME Nodal test case the interface emulated is a S11 interface, so is normal Landslide does not answer the message.
When CSR message has been correctly forwarded, the problem persisted. This time emulated SGW did not responded because the CSR message has a VLAN tag configured. So it was necessary to configure the same VLAN tag as MME S11 configuration.
