HP MSR2000/3000/4000 Router Series Layer 3 - IP Routing Command Reference

503
Usage guidelines
Each LSA in the LSDB has an age that is incremented by 1 every second, but the age does not change
during transmission. Therefore, it is necessary to add a transmission delay into the age time, especially
for low-speed links.
Examples
# Configure the transmission delay as 3 seconds for Ethernet 1/1 in instance 1.
<Sysname> system-view
[Sysname] interface ethernet 1/1
[Sysname-Ethernet1/1] ospfv3 trans-delay 3 instance 1
preference
Use preference to specify a preference for OSPFv3 routes.
Use undo preference to restore the default.
Syntax
preference [ ase ] [ route-policy route-policy-name ] preference
undo preference [ ase ]
Default
The preference for OSPFv3 internal routes is 10, and that for OSPFv3 external routes is 150.
Views

Predefined user roles

Parameters
ase: Sets a preference to OSPFv3 external routes. If the keyword is not specified, the command sets a
preference for OSPFv3 internal routes.
route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63
characters, to set a preference for matching routes.
preference: Specifies the preference of OSPFv3, in the range of 1 to 255. The smaller the value, the
higher the preference.
Usage guidelines
If multiple routing protocols find multiple routes to the same destination, the router uses the route found by
the protocol with the highest preference.
Examples
# Set a preference of 150 for OSPFv3 routes.
<Sysname> system-view
[Sysname] OSPFv3
[Sysname-OSPFv3-1] preference 150
