SLB deployment scheme.
Hello,
Can you please help me, to understand the principle of SLB operations? I see in documentation that SLB and SBCs communicate via tunnels. SLB expects to get the messages from users on 'service-port'.
The question is: can 'service-port' be organized on the same IP address as a tunnel? In other words, SLB receives the messages from UEs on service-port 192.168.1.3:5060 and forwards them to SBC1 192.168.1.1 and SBC2 192.168.1.2 via port 4444 ?
What happens in case if 'service-port' and tunnel termination port are separated? Will SLB forward messages in a PBRB manner :
Or forward them externally from service-port (1) to tunnel termination point (2) and then via tunnel to SBC1 ? In other words do we need to configure external routing between "SLB Access realm" and "SBC Access realm"
