Introduction Verizon Wireless Dynamic Mobile Network Routing (DMNR) 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. It enables integration between wireless and wireline enterprise services (fourth-generation [4G] wireless WAN [WWAN]) by using the Mobile IPv4 NEtwork MObility (NeMo) protocol, without the need for end-to-end overlay tunneling.
. ISR 1900, 2900, 3900 and 4000 series require an IOS Software data license for MPN/DMNR (NeMo support). This is included by default with 800 series. The data license is acquired by ordering the AppX license. A 60 day temporary data license can be immediately generated using an IOS configuration mode command (requires an IOS reload to take effect). Below are examples for ISR G2 and 4K series. license boot module c1900 technology-package datak9.
12. Ensure that no static routes pointing to interface Cellular 0/x/0 (Cellular 0 for 819 and 899) exist in the mobile router configuration. 13. The dynamic Tunnel0 interface will have the IP maximum transmission unit (MTU) of 1476 bytes. IP packets whose lengths exceed 1440 bytes will require fragmentation. For TCP traffic the ip tcp adjust-mss command may be used as shown in this guide to avoid fragmentation.
Always-On Backup Access Design Requirements This configuration example is based on the following logical design requirements: 1. When the primary circuit is operational, the backup wireless/NEMO session must be connected. 2. Switch to backup must be triggered by the physical or logical failure on the primary circuit (such as loss of routing). 3. Only select traffic from the branch office will be allowed to use the backup wireless link. 4.
