OSPF Configuration Commands 213 Using the undo ospf timer retransmit command, you can restore the default interval value for LSA re-transmission on an interface. When a router transmits a Link State Advertisement (LSA) to the peer, it waits for the acknowledgement packet. If no acknowledgement is received from the neighbor within the time you set using this command, the LSA is re-transmitted. According to RFC2328, the LSA retransmit between adjacent routers should not be set too short to avoid unexpected re-transmission. Example To set the retransmit interval between the interface Vlan-interface 1 and the adjacent routers to 12 seconds, enter the following: system-view System View: return to User View with Ctrl+Z. [SW5500]interface Vlan-interface 1 [SW5500-Vlan-interface1]ospf timer retransmit 12 ospf trans-delay Syntax ospf trans-delay value undo ospf trans-delay View VLAN Interface view Parameter value Enter the LSA transmission delay, in seconds, in the range 1 to 3600. By default, the value is 1 second. Description Using the ospf trans-delay command, you can configure the LSA transmission delay on an interface. Using the undo ospf trans-delay command, you can restore the default value of the LSA transmission delay. LSA will age in the "link state database" (LSDB) of the router as time goes by (add 1 for every second), but it will not age during network transmission. Therefore, it is necessary to add a period of time set by this command to the aging time of LSA before transmitting it. Example To set the LSA transmission delay to three seconds on interface Vlan-interface 1, enter the following: system-view System View: return to User View with Ctrl+Z.
