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. It enables integration between wireless and wireline enterprise services (4G Wireless
WAN) by making use of the Mobile IPv4 NEtwork MObility (NEMO) protocol and without the need for end to end
overlay tunneling.
Dynamic Mobile Network Routing (DMNR) is part of the Verizon Wireless Mobile Private Network. DMNR is
compatible with the Cisco IOS Mobile IP Mobile Networks feature. DMNR makes use of the Collocated-Care-of-
Address (CCOA) option and supports IP sub-net registration, routing and forwarding.
This configuration guide shows an example using Verizon Wireless DMNR service with always-on 4G LTE access for
the purpose of providing backup communications between two co-located redundant branch routers.
The always-on backup configuration shown in this example can be used to maintain the backup routing path all the
time and switch to it based on loss of routing over the primary path through the primary router. Since the connection
and routing state of the backup path is always maintained the switch to backup does not involve the time to activate
the wireless and NEMO sessions.
Notes
1.
Cisco Integrated Services Routers Generation 2 (ISR G2) and CGR routers with integrated 4G LTE cards are
supported (V or VZ SKUs, 1900, 2900, 3900, and CGR2010 Series with LTE GRWIC). Cisco 819 and 899 ISRs
with embedded LTE are supported. Cisco ISR 4Ks (4321, 4331, 4351, 4431, 4451) with LTE NIM are supported.
2.
The minimum Cisco IOS software release depends on the LTE modem firmware level (seen via IOS command
“show cell 0/x/0 hardware” for LTE eHWIC/NIM/GRWIC, “show cell 0 hardware” for 819/899).
a.
EHWIC-4G-LTE-V, C819G-4G-V-K9, GRWIC-4G-LTE-V: Firmware release 1.0.9.3 is no longer
recommended. It should be upgraded to firmware 3.5.10.6. IOS 15.2(4M2) should be used to
upgrade the firmware. Firmware 3.5.10.6 and install insructions are available at:
b.
EHWIC-4G-LTE-V, C819G-4G-V-K9, GRWIC-4G-LTE-V: Firmware release 3.5.10.6 is the
recommended release: The IOS recommended release with LTE firmware 3.5.10.6 is IOS 15.5(2)T
or later T release.
c.
EHWIC-4G-LTE-VZ, NIM-4G-LTE-VZ, 8x9 VZ models (XLTE models):
Firmware release 5.5.58.1 is the minimum release. The recommended IOS release is 15.5(2)T or
later T release for ISR 1900/2900/3900 series, and IOS XE 3.16 for ISR 4000 series.
3.
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
. The keyword following "module" varies based on ISR
model c1900, c2900, c3900. For ISR 4000 series, the configuration mode command is as follows:
license boot level appxk9
the command is the same for all ISR 4K models.
