说明
vtysh is an integrated command shell for FRRouting (FRR) and Quagga routing software. It provides a unified Cisco IOS-like CLI for configuring and monitoring all routing daemons (Zebra, BGP, OSPF, RIP, IS-IS, etc.) from a single interface. The shell operates in hierarchical modes: User EXEC mode for basic commands, Privileged EXEC mode (via enable) for administrative commands, and Configuration mode (via configure terminal) for making changes. Each routing protocol has its own configuration sub-mode. vtysh connects to all running routing daemons through their control sockets, presenting their combined functionality. Commands like show ip route, show bgp summary, and show running-config aggregate information from all relevant daemons. Configuration can be saved with write memory to the integrated config file (/etc/frr/frr.conf) or individual daemon configs.
