ISR Redundancy Guide for Verizon Wireless DMNR and 4G LTE Overview Verizon Wireless Dynamic Mobile Network Routing is a network-based Mobile IP technology capable of providing dynamic routing and support for mobile or stationary enterprise routers in primary wireless access or automatic wireless backup configurations.
ISR Redundancy Guide for Verizon Wireless DMNR and 4G LTE 4. To connect a Network Mobility (NEMO) session to the Verizon Wireless Enterprise GateWay (EXGW), the enterprise MPN must be provisioned for 4G, and the subscriber mobile line (subscriber identity module [SIM]) used by the mobile router enhanced high-speed WAN interface card (eHWIC, NIM or GRWIC or embedded in an 819 or 899) must have NEMO permission provisioned by Verizon Wireless.

The Verizon Wireless Network will preserve the quality-of-service (QoS) markings (type of service/differentiated services code point [ToS/DSCP]) that have been set in the original IP packet header. 16. The changes to the subnet (prefix) list registered by the mobile router take effect on EXGW immediately while the NEMO session is running. No coordination is needed to advertise new subnets beyond ISR configuration. 17.
ISR Redundancy Guide for Verizon Wireless DMNR and 4G LTE Always-On Backup Access Design Requirements and Recommendations When the primary circuit is operational the backup wireless/NEMO session shall be connected. Switch to backup shall be triggered by physical or logical failure on the primary circuit (e.g. loss of routing). Once the primary circuit is restored all traffic shall be reverted to the primary path.

If this object changes state to line-protocol down the router’s HSRP application will decrement the HSRP priority of the F0/0 interface by 20, making the NEMO router LAN interface the active HSRP interface.
