Configuring An Ospfv3 Virtual Link - 3Com S7906E Configuration Manual

To do...
Enter system view
Enter OSPFv3 view
Enter OSPFv3 area view
Configure the area as a stub
area
Specify a cost for the default
route advertised to the stub
area
You cannot remove an OSPFv3 area directly. Only when you remove all configurations in area
view and all interfaces attached to the area become down, can the area be removed.
All the routers attached to a stub area must be configured with the stub command. The keyword
no-summary is only available on the ABR of the stub area.
If you use the stub command with the keyword no-summary on an ABR, the ABR advertises a
default route in an Inter-Area-Prefix-LSA into the stub area. No AS-external-LSA,
Inter-Area-Prefix-LSA or Inter-Area-Router-LSA is advertised in the area. The stub area of this kind
is also known as a totally stub area.
