Brocade ICX 6650 Layer 3 Routing Configuration Guide 233

OSPF V3 configuration
The ethernet | loopback | tunnel | ve parameter specifies the interface from which the router
derives the source IPv6 address for communication across the virtual link. If you specify an
Ethernet interface, also specify the port number associated with the interface. If you specify a
loopback, tunnel, or VE interface, also specify the number associated with the respective interface.
To delete the source address for the virtual link, use the no form of this command.
Modifying virtual link parameters
You can modify the following virtual link parameters:
•Dead-interval: The number of seconds that a neighbor router waits for a hello packet from the
current router before declaring the router is down. The range is 1 – 65535 seconds. The
default is 40 seconds.
•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.
NOTE
The values of the dead-interval and hello-interval parameters must be the same at both ends of a
virtual link. Therefore, if you modify the values of these parameters at one end of a virtual link, you
must remember to make the same modifications on the other end of the link.
The values of the other virtual link parameters do not require synchronization.
For example, to change the dead interval to 60 seconds on the virtual links defined on ABR1 and
ABR2, enter the following command on ABR1.
Brocade(config-ospf6-router)#area 1 virtual-link 192.168.22.1
dead-interval 60
Enter the following command on ABR2.
Brocade(config-ospf6-router)#area 1 virtual-link 10.0.0.1 dead-interval 60
Syntax: area number | ipv4-address virtual-link router-id [dead-interval seconds | hello-interval
seconds | retransmit-interval seconds | transmit-delay seconds]
The area number | ipv4-address parameter specifies the transit area.
The router-id parameter specifies the router ID of the OSPF router at the remote end of the virtual
link. To display the router ID on a router, enter the show ip command.
The dead-interval, hello-interval, retransmit-interval, and transmit-delay parameters are discussed
earlier in this section.
