Use this reference to understand Linux iproute2 commands for network configuration and inspection. It explains `ip` syntax, objects such as addresses and routes, selectors and values, plus related `ss`, `bridge`, and `tc` commands.
Use when working with the Linux iproute2 networking commands — ip, ss, bridge, tc, and related tools. Covers the ip command argument structure, object types (address, link, route, rule, neighbour, tunnel, xfrm, netns, mptcp, ioam, l2tp, etc.), subcommands, selectors, and value types. Triggers on: "iproute2", "ip command", "ip address", "ip link", "ip route", "ip rule", "ip neighbour", "ip neigh", "ip tunnel", "ip xfrm", "ip netns", "ip mptcp", "ip ioam", "ip l2tp", "ip vrf", "ip token", "ip ntable", "ip tcp_metrics", "ip maddress", "ip mroute", "ip mrule", "ip addrlabel", "ip tuntap", "ip monitor", "ip stats", "ip nexthop", "ip netconf", "ip fou", "ip macsec", "ip sr", "ss command", "bridge command", "tc command", "IFADDR", "CONFFLAG", "SELECTOR", "ROUTE", "NUD state", "addrlabel", "ipproto".
