PLANET XGS3-24040 - Manual (Page 493)

34-206
Function:
Configure a logical link between two backbone areas physically divided by non-backbone area. The “no
area <id> virtual-link A.B.C.D [instance-id <instance-id> | INTERVAL]” command removes this
virtual-link.
Parameter: <id> is the area number which could be digits ranging between 0～4294967295, and also as
an IP address.
<instance-id> is the interface instance ID ranging between 0~255 and defaulted at 0
INTERVAL= [dead-interval|hello-interval|retransmit-interval|transmit-delay]
<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, 1 second by default
Default:
No default configuration.
Command Mode:
OSPFv3 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 areas 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 ipv6 ospf
Switch(config-router) #area 1 virtual-link 10.10.11.50 hello 5 dead 20
Switch(config-router) #area 1 virtual-link 10.10.11.50 instance-id 1
34.5 abr-type
Command:
abr-type {cisco|ibm| standard}
no abr-type [cisco|ibm| standard]
Function:
Configure an OSPF ABR type with this command. The “no abr-type [cisco|ibm| standard]” command
restores the default.
Parameter: cisco, realize by cisco ABR; ibm, realize by ibm ABR; shortcut, specify a shortcut-ABR;
