Configuring OSPF
The parameters are described below. For syntax information, at the CLI
prompt, enter the command area help.
Virtual Link Parameter Descriptions
You can modify the following virtual link interface parameters:
Authentication Key: This parameter allows you to assign different authen-
tication methods on a per-virtual-link basis. OSPF supports two methods of
authentication for each interface—none and simple password. Only one
method of authentication can be active on a virtual link at a time.
The simple password method of authentication requires you to configure an
alphanumeric password on an interface. The password can be up to eight
characters long. The simple password setting takes effect immediately. All
OSPF packets transmitted on the interface contain this password. All OSPF
packets received on the interface are checked for this password. If the
password is not present, then the packet is dropped.
Hello Interval: The length of time between the transmission of hello packets.
The range is 1 – 65535 seconds. The default is 10 seconds.
Retransmit Interval: The interval between the re-transmission of link state
advertisements to router adjacencies for this interface. The range is 0 – 3600
seconds. The default is 5 seconds.
Transmit Delay: The period of time it takes to transmit Link State Update
packets on the interface. The range is 0 – 3600 seconds. The default is 1 second.
Dead Interval: The number of seconds that a neighbor router waits for a
hello packet from the current routing switch before declaring the routing
switch down. The range is 1 – 65535 seconds. The default is 40 seconds.
Define Redistribution Filters
Route redistribution imports and translates different protocol routes into a
specified protocol type. On HP Series 5300XL Switches, redistribution is
supported for only static routes and directly connected routes. Redistribution
of any other routing protocol into OSPF is not currently supported. When you
configure redistribution for OSPF, you can specify that static or connected
routes are imported into OSPF routes. Likewise, RIP redistribution supports
the import of static or connected routes into RIP routes.
To configure for redistribution, define the redistribution tables with restrict
redistribution filters. In the CLI, use the restrict command for OSPF at the
OSPF router level.
