LSP attributes include the generation interval, maximum transmission unit (MTU) or size, and the refresh interval. You can modify the LSP attribute defaults, but it is not necessary. To change the defaults, use any or all of the following commands in ROUTER ISIS mode: Command Syntax lsp-gen-interval [level-1 | level-2] seconds lsp-mtu size lsp-refresh-interval seconds max-lsp-lifetime seconds Command Mode Purpose ROUTER ISIS ROUTER ISIS ROUTER ISIS ROUTER ISIS Set interval between LSP generation. • seconds range: 0 to 120 Default is 5 seconds. Default level is Level 1. Set the LSP size. • size range: 128 to 9195. Default is 1497. Set the LSP refresh interval. • seconds range: 1 to 65535. Default is 900 seconds. Set the maximum time LSPs lifetime. • seconds range: 1 to 65535 Default is 1200 seconds. To view the configuration, use the show config command in ROUTER ISIS mode or the show running-config isis command in EXEC Privilege mode (Figure 475). 526 | Intermediate System to Intermediate System
