To view all interfaces configured with IS-IS routing along with the defaults, use the show isis interface command in EXEC Privilege mode. Dell#show isis interface G1/34 GigabitEthernet 2/10 is up, line protocol is up MTU 1497, Encapsulation SAP Routing Protocol: IS-IS Circuit Type: Level-1-2 Interface Index 0x62cc03a, Local circuit ID 1 Level-1 Metric: 10, Priority: 64, Circuit ID: 0000.0000.000B.01 Hello Interval: 10, Hello Multiplier: 3, CSNP Interval: 10 Number of active level-1 adjacencies: 1 Level-2 Metric: 10, Priority: 64, Circuit ID: 0000.0000.000B.01 Hello Interval: 10, Hello Multiplier: 3, CSNP Interval: 10 Number of active level-2 adjacencies: 1 Next IS-IS LAN Level-1 Hello in 4 seconds Next IS-IS LAN Level-2 Hello in 6 seconds LSP Interval: 33 Next IS-IS LAN Level-1 Hello in 4 seconds Next IS-IS LAN Level-2 Hello in 6 seconds LSP Interval: 33 Restart Capable Neighbors: 2, In Start: 0, In Restart: 0 Dell# Changing LSP Attributes IS-IS routers flood link state PDUs (LSPs) to exchange routing information. 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. • Set interval between LSP generation. ROUTER ISIS mode lsp-gen-interval [level-1 | level-2] seconds - seconds: the range is from 0 to 120. The default is 5 seconds. The default level is Level 1. • Set the LSP size. ROUTER ISIS mode lsp-mtu size - size: the range is from 128 to 9195. The default is 1497. • Set the LSP refresh interval. ROUTER ISIS mode lsp-refresh-interval seconds - seconds: the range is from 1 to 65535. The default is 900 seconds. • Set the maximum time LSPs lifetime.
