Introduction
BGPv4 is a path-vector routing protocol where routing decisions are made based on the policies or rules laid
out by the network administrator. It is typically used where networks are multi-homed between multiple Internet
Service Providers, or in very large internal networks where internal gateway protocols do not scale sufficiently.
• RIP (Routing Information Protocol)
RIP version 1 and version 2 are distance-vector routing protocols that limit the number of router hops to 15
when determining the best routing path. This protocol is typically used on small, self-contained networks, as
any router beyond 15 hops is considered unreachable.
• IS-IS (Intermediate System - Intermediate System)
IS-IS is one of a suite of routing protocols tasked with sharing routing information between routers. The job of
the router is to enable the efficient movement of data over sometimes complex networks. Routing protocols are
designed to share routing information across these networks and use sophisticated algorithms to decide the
shortest route for the information to travel from point A to point B. One of the first link-state routing protocols
was IS-IS developed in 1985 and adopted by the ISO in 1998 (ISO/IEC 10589:2002). It was later republished
as an IETF standard
• Brute Force Attack Prevention
Protection against Brute Force Attacks (BFAs) is standard in ROX II. If an external host fails to log in to the
CLI, NETCONF or Web interfaces after a fixed number of attempts, the host's IP address will be blocked for a
period of time. That period of time will increase if the host continues to fail on subsequent attempts.

• USB Mass Storage
Use a removable USB Mass Storage drive to manage important files and configure ROX II.
▪ Configure ROX II from the USB — Configure ROX II to read configuration files and feature keys from the
USB Mass Storage drive on startup, rather than any local files saved on the device. This allows for quick,
portable configuration of any ROX II device.
▪ Upgrade/Downgrade Firmware — Use the USB Mass Storage drive as a portable repository for new or
legacy versions of the ROX II firmware.
▪ Backup Files — Configure ROX II to backup important information to the USB Mass Storage drive, such as
rollbacks, log files, feature keys and configuration files.
IMPORTANT!
Do not remove the USB Mass Storage drive during a file transfer.
NOTE
Only USB Mass Storage drives with one partition are supported.
• Hot Swapping Modules
Power Modules (PM) and Line Modules (LM) can be safely replaced with modules of exactly the same type
while the device is running, with minimal disruption to the network. The device only needs to be restarted after
swapping a module with a different type, such as an Ethernet module with a serial module.
Following a hot swap, the new module will be automatically configured to operate in the same operational state
as the previous module.
