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.

Usage
Use this command to enable the default flex functionality without exposing the pool (flex) structure. This
functionality provides a means for SGSNs outside of the pool to reach a pooled SGSN on the basis of its NRI.
