Configuring the Interval for Retransmitting LSAs to Neighboring Switches

Procedure

1. Run system-view

   The system view is displayed.

2. Run interface interface-type interface-number

   The interface view is displayed.

3. On an Ethernet interface, run undo portswitch

   The interface is switched to Layer 3 mode.

   By default, an Ethernet interface works in Layer 2 mode.

   The mode switching function takes effect when the interface only has attribute configurations (for example, shutdown and description configurations). Alternatively, if configuration information supported by both Layer 2 and Layer 3 interfaces exists (for example, mode lacp and lacp system-id configurations), no configuration that is not supported after the working mode of the interface is switched can exist. If unsupported configurations exist on the interface, delete the configurations first and then run the undo portswitch command.

   If many Ethernet interfaces need to be switched to Layer 3 mode, run the undo portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view to switch these interfaces to Layer 3 mode in batches.

4. Run ospfv3 timer retransmit interval [ instance instance-id ]

   The interval for retransmitting LSAs to the adjacent routers is set.

   The value of seconds must be greater than a round trip of one packet transmitted between two switches.

   Do not set a value which is too small, for the interval between LSA retransmissions. Otherwise, unnecessary retransmissions may occur.

5. Run commit

   The configuration is committed.
