Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
Free Range Routing or FRRouting or FRR is a network routing software suite running on Unix-like platforms, particularly Linux, Solaris, OpenBSD, FreeBSD and NetBSD. Gargoyle: Active: Linux distribution: MIPS, x86-64: A free OpenWrt-based Linux distribution for a range of Broadcom and Atheros chipset based wireless routers. Global Technology ...

Zero-configuration networking (zeroconf) is a set of technologies that automatically creates a usable computer network based on the Internet Protocol Suite (TCP/IP) when computers or network peripherals are interconnected. It does not require manual operator intervention or special configuration servers.
tc relates to the Linux kernel packet scheduler as iptables to netfilter. Both are user-space CLI programs that are used to configure their respective Linux kernel subsystem. tc (traffic control) is the user-space system administration utility program used to configure the Linux kernel packet scheduler.
On Linux, tracepath is a utility similar to traceroute, with the primary difference of not requiring superuser privileges. [ 12 ] Cisco 's implementation of traceroute also uses a sequence of UDP datagrams, each with incrementing TTL values, to an invalid port number at the remote host; by default, UDP port 33434 is used.
When a multicast packet enters a router's interface, the router looks up the list of networks that are reachable via that interface (i.e., it checks the paths by which the packet could have arrived). If the router finds a matching routing entry for the source IP address of the multicast packet, the RPF check passes and the packet is forwarded ...
In Linux distributions based on 2.2.x Linux kernels, the ifconfig and route commands are operated together to connect a computer to a network, and to define routes between computer networks. Distributions based on later kernels have deprecated ifconfig and route, replacing them with iproute2. Route for Linux was originally written by Fred N ...
