HP 6125XLG R2306-HP 6125XLG Blade Switch TRILL Configuration Guide - Page 12

Step 1. Enter system view. 2. Enter Ethernet or aggregate interface view. Command system-view interface interface-type interface-number 3. Configure the Hello interval. trill timer hello interval 4. Configure the Hello multiplier. trill timer holding-multiplier count 5. Configure the inhibition time. trill timer avf-inhibited time 6. Configure the CSNP interval. trill timer csnp interval Remarks N/A N/A The default setting is 10 seconds. This command sets the Hello interval for the RB. The Hello interval of the DRB is 1/3 of the Hello interval of the RB, so that the DRB failures can be quickly detected. The default setting is 3. The default setting is 30 seconds. The default setting is 10 seconds. Adjusting LSP parameters You can modify the following LSP parameters: • LSP maximum age-An LSP originated by an RB uses the maximum age as the remaining lifetime. When the remaining lifetime of an LSP in the LSDB is 0 seconds, the RB removes the LSP's content, keeps the LSP's digest, and purges the LSP from the network by advertising the LSP that has the remaining lifetime set to 0. • LSP refresh interval-When the remaining lifetime of a locally originated LSP is no greater than (maximum age - refresh interval), the LSP is refreshed even if no change occurs to it. This mechanism avoids frequent LSP aging and ensures network stability. • Minimum LSP interval and maximum number of LSPs transmitted per time-To avoid frequent LSP aging in the network, RBs periodically advertise LSPs. The actual refresh interval of an LSP is determined by both the minimum LSP interval and the maximum number of LSPs transmitted per time. To prevent LSPs from being aged out accidentally, set the LSP maximum age and the LSP refresh interval appropriately. To adjust LSP-related parameters: Step 1. Enter system view. 2. Enter TRILL view. 3. Set the LSP maximum age. 4. Set the LSP refresh interval. 5. Return to system view. Command system-view trill timer lsp-max-age time timer lsp-refresh time quit Remarks N/A N/A The default setting is 1200 seconds. The default setting is 900 seconds. N/A 9
