How it Works
This section describes how this feature works.
The UDP Proxy merge mode is a prerequisite for this feature.
-
For a sunny-day scenario, RACK1 (GTPC-EP Active Instance-1) and RACK2 (GTPC-EP Active Instance-2) handle the traffic from GR-Instance-1 and GR Instance-2, respectively.
-
For a rainy-day scenario, the GR Instance-1 (S11, S5E, S5) and GR Instance-2 (S11, S5E, S5) traffic splits between two GTPC-EP instances.
In the rainy-day scenario, assuming RACK2 is down, RACK1 handles all the traffic for GR Instance-1 and GR Instance-2. With the GR Split implementation, the GTPC-EP Active Instance-1 handles GTP traffic for all the interfaces for GR Instance-1, and GTPC-EP Active Instance-2 handles all the GTP traffic for GR Instance-2.
