pool
This command enables the default S4-SGSN functionality for (flex) pooling and enables inclusion of the
configured pool hop-counter count in new SGSN context/identity request messages. This command supports
S4-SGSN pooling across the S16 interface. The S16 interface provides a GTPv2 path to a peer S4-SGSN.
Support for this interface is provided as part of the S4 interface license. This command sets the S4-SGSN as
the default SGSN within a pool. If the default S4-SGSN receives an inbound SGSN context request, it forwards
it to the right SGSN in the pool based on the NRI bits of the P-TMSI.
