AUTH_KEY= authentication-key <key>
<key>: A password consists of less than 8 characters
INTERVAL= [dead-interval|hello-interval|retransmit-interval|transmit-delay] <value>
<value>:>:
The delay or interval seconds, ranging between 1~65535
<dead-interval>:
A neighbor is considered offline for certain dead interval without its
group messages which the default is 40 seconds.
<hello-interval>:
The time interval before the router sends a hello group message,
default is 10 seconds
<retransmit-interval>:
The time interval before a router retransmitting a group
message, default is 5 seconds.
<transmit-delay>:
The time delay before a router sending a group messages,
default is 1 second
Default:
None
Command Mode:
OSPF protocol mode
Usage Guide:
In the OSPF all non-backbone areas will be connected to a backbone
area. If the connection to the backbone area is lost, virtual link will repair this connection.
You can configure virtual link between any two backbone area routers connected with the
public non-backbone area. The protocol treat routers connected by virtual links as a
point-to-point network.
Example:
Switch#config terminal
Switch(config) #router ospf 100
Switch(config-router) #area 1 virtual-link 10.10.11.50 hello 5 dead 20
Relevant Commands: area authentication, show ip ospf, show ip ospf virtual-links
13.6.3.9 auto-cost reference-bandwidth
Command: auto-cost reference-bandwidth <bandwith>
no auto-cost reference-bandwidth
Function:
This command sets the way in which OSPF calculate the default metric value.
The “no auto-cost reference-bandwidth” command only configures the cost to the
interface by types.
Parameter:
<bandwith> reference bandwidth in Mbps, ranging between 1~4294967
Default:
Default bandwidth is 100Mbps
Command Mode:
OSPF protocol mode
Usage Guide:
The interface metric value is acquired by divide the interface bandwith
with reference bandwidth. This command is mainly for differentiate high bandwidth links.
If several high bandwidth links exist, their cost can be assorted by configuring a larger
reference bandwidth value.
