Description
Allows the entry of an OSPF Area ID − previously defined on the Switch −
that allows a remote area to communicate with the backbone (area 0). A
Transit Area cannot be a Stub Area or a Backbone Area.
The OSPF router ID for the remote router. This is a 32-bit number in the
form of an IP address (xxx.xxx.xxx.xxx) that uniquely identifies the remote
area's Area Border Router.
Specify the interval between the transmission of OSPF Hello packets, in
seconds. Enter a value between 1 and 65535 seconds. The Hello
Interval, Dead Interval, Authorization Type, and Authorization Key should
have identical settings for all routers on the same network.
Specify the length of time between (receiving) Hello packets from a
neighbor router before the selected area declares that router down. Again,
all routers on the network should use the same setting.
If using authorization for OSPF routers, select the type being used. MD5
key authorization must be set up in the MD5 Key Settings menu.
Enter a case-sensitive password for simple authorization or enter the MD5
key you set in the MD5 Key settings menu.
NOTE: For OSPF to function properly some settings should be identical
on all participating OSPF devices. These settings include the Hello Interval
and Dead Interval. For networks using authorization for OSPF devices,
they Authorization Type and Password or Key used must likewise be
identical.
