Router Best Practices and Selection Guide with Verizon Wireless 4G LTE

enabling cookie-cutter remote site VPN configuration (all identical) compared to traditional methods. A prerequisite for

GETVPN is routing to/from any subnet behind mobile routers, and is met by DMNR.

Integration of 4G into private network deployments: Simply supporting 4G as an IP interface may not be sufficient

to enable a router’s use in a private network. The LTE interface should support similar private network features as a

wireline interface (as is feasible) and not inhibit users’ access to business functions. This entails both the actual

features, and the interaction between features. For example, a router may be able to support IP routing protocols, and

support VPN, but be unable to support routing protocols across the VPN (which may be required for appropriate

routing within the private network). An additional 5 integration examples are below.

Integration into an existing Virtual Private Network: The need for CPE-based VPN network overlay may be

preferred, or the option of supporting a network-based highly scalable, easily deployed option may be best.

The CPE which supports both methods and multiple options for each will provide flexibility and growth. The

Cisco ISR supports NeMo, PMIPv6 (the IPv6 equivalent), IPsec, IPsec/GRE, DMVPN (with VRF support),

Note that not every VPN type is supported by every network service. Contact Verizon for details.

Integration with an existing private network: Support for multiple WAN connections and a variety of IP and

non-IP routing protocols allows for supporting various existing private network designs. The Cisco ISR

supports multiple interfaces simultaneously with load sharing, including multiple LTE interfaces/radios. Note

that not every ISR feature is supported by every network service. For example, multiple LTE radios can be

used simultaneously with DMNR, with one in primary and one in backup mode. To use multiple LTE radios

simultaneously with DMNR, one interface would connect to DMNR and one or more interfaces would connect

to Verizon public network service for Internet access or customer-prem-based VPN.

Integration with a wide variety of routing protocols: The ISR also supports RIP, OSPF, BGP, IS-IS, PfR,

LISP, policy-based routing, and static routes, along with HSRP and VRRP for high availability.

Integration with other routing functions: The LTE interface should be configurable and manageable as other

WAN interfaces. This includes robust diagnostics (e.g. LTE DM logging), 4G SNMP MIBs, support for IP

routing protocols and VPN technologies across the LTE interface, control of radio technology selection (4G

only, 2G/3G/4G with failover/fallback). The ISR supports these functions.

Quality of Service (QoS). The LTE interface should be able to mark, classify, prioritize, and rate limit user

traffic based on its importance to the organization.

GPS location and time sync integration, and automation. This includes displaying, recording and sending of

location information, geo-fencing (enforcement to only operate within a certain geographical area), setting the

router clocks via the GPS time source, time or event-based LTE connect/disconnect. The Cisco ISR can

support these functions.

Support SIM security (ability to lock, unlock, change the PIN of the SIM to ensure it cannot be used in another

device and allow unauthorized access to the network. This Cisco ISR can support this function.
