OMMANDS

seconds: Transmission delay in seconds, ranging from 1 to 3600. The default is 1.

instance-id: The instance ID of an interface, in the range of 0 to 255, with the 
default as 0.

Use the ospfv3 trans-delay command to configure the transmission delay for 
an interface with an instance ID.

Use the undo ospfv3 trans-delay command to restore the default.

The transmission delay defaults to 1s.

As LSAs are aged in the LSDB (incremented 1 by each second) but not aged on 
transmission, it is necessary to add a delay time to the age time before sending a 
LSA. This configuration is important for low-speed networks.

# Configure the transmission delay as 3 seconds for an interface of instance 1.

ase: Applies the preference to OSPFv3 external routes. If the keyword is not 
specified, the preference applies to OSPFv3 internal routes.

route-policy route-policy-name: References a routing policy to set preference for 
specific routes. The name is a string of 1 to 19 characters.

preference: Preference of OSPFv3, in the range 1 to 255.

Use the preference command to specify a preference for OSPFv3 routes.

Use the undo preference command to restore the default.

By default, the preference for OSPFv3 internal routes is 10, and that for OSPFv3 
external routes is 150.

The smaller the value is, the higher the preference is.

A router may run multiple routing protocols. Each protocol has a preference. 
When several routing protocols find multiple routes to the same destination, the 
route found by the protocol with the highest preference is selected.

# Set a preference of 150 for OSPFv3 routes.
