Any failure on either the authentication or authorize of a NEMO MIPv4 session shall not affect the underlying PDN

security credentials do not match between the MR NEMO client and NEMO4G-HA, NEMO4G-HA can reject the
NEMO MIPv4 RRQ, but the associated PDN connection shall not be terminated.

NEMO Session Timers
NEMO4G-HA uses the registration lifetime value locally configured, even though MR's may use the maximum possible

NEMO4G-HA can process ad-hoc NEMO RRQ messages.
Enterprise-wide Route Limit Control
NEMO4G-HA supports a control mechanism to limit the maximum number of prefixes/routes that a given enterprise
can register, including the pools for WAN IP assignments.

When the maximum number of routes is reached, a syslog message is generated. Once the number of routes goes under
the limit, a syslog message is generated for notification. And no further routes are accepted into the VRF route table.

Forced Fragmentation
HA/PGW/GGSN forces IP packet fragmentation even for IP packets with the DF-bit set from enterprise to mobile.
From mobile to enterprise DF-bit is honored.

Redundancy/Reliability
CDMA, eHRPD and LTE all support intra-chassis Session Redundancy (SR) and Inter-Chassis Session Redundancy
(ICSR) functionalities.
