3Com Switch 7750 Series
Command Reference Guide – Routing Protocol Chapter 4 Integrated IS-IS Configuration Commands
4-26
Description
Use the isis timer retransmit command to configure the time interval for
retransmitting LSP packets over point-to-point link.
Use the undo isis timer retransmit command to resume the default configuration.
You should be careful when configuring this parameter to avoid unnecessary
retransmission.
You need not use this command over a broadcast link, because a LAP packet
requires response from the peer only over a point-to-point link, but not over a
broadcast link,
Related command: isis timer lsp.

# Configure the time interval as 10 seconds for Vlan-interface 10 to retransmit LSP.
