Verizon Goes Nationwide With LTE CAT-M IoT Network
The network is built on a virtualized cloud environment.
Network Device Authentication with Ansible 2.3
In a recent post, Coming Soon: Networking Features in Ansible 2.3, one of the key features to be introduced is a new connection framework. This new connection framework supports persistent SSH connections for modules that communicate with network devices via two methods:
1) the tried and true CLI method
2) the newly included NETCONF method
With the new connection framework, the network modules are currently undergoing a transformation with regards to how credentials are supplied. In Ansible versions 2.0 to 2.2, network modules support providing connection credentials as top-level arguments in the module.
If you want to build a task using the ios_command Ansible module the credentials used to authenticate to the device could be provided as top level arguments. The following example demonstrates the simplest form of passing credentials to modules in order to authenticate to the remote device:
ios_command:
commands: show version
host: “{{ inventory_hostname }}”
username: cisco
password: cisco
In some cases, such as with configuration modules, additional authentication details are required. In order to enter configuration mode, the Playbook tasks must first enter “enable” mode and, in some cases, supply an enable-mode password. Notice the additional two arguments (authorize and auth_pass) added to Continue reading
PQ Show 109: A Look Inside DMEVPN
On today s Priority Queue, we explore DMEVPN, a open-source technology for multipoint EVPN tunnels. By using DMEVPN, network engineers can extend layer-2 tunnels across an IP network.

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
In the gap between plug and play unmanaged Ethernet switches and fully managed enterprise switches, vendors added the so called “smart switch,” which offer light management features to unmanaged gigabit Ethernet devices. Today, smart switches targeted at small-to-medium-size business run the gamut in terms of manageability and feature sets.
The appeal of basic network management features for a small business stems from the need for performance and security. Plug and play and start right away—that’s what every start up wants—then later on, they need basic configurations and features to accommodate growth as needed.
