4.6.6.5.4 Displaying the Virtual Neighbor Table
Virtual links can be used to link an area isolated from the backbone, to create a redundant link between
any area and the backbone to help prevent partitioning, or to connect two existing backbone areas into a
common backbone. Note that the processes of establishing a active link between virtual neighbors is
similar to that used for physically adjacent neighbors..
Parameter Description
Area ID The transit area the virtual link must cross to connect the border routers.
Router ID The OSPF identifier for the router at the other end of the link.
IP Address IP address of the border router at the other end of the link.
Option The optional OSPF capabilities supported by the neighbor. The neighbor's
optional OSPF capabilities are also listed in its Hello packets. This enables
received Hellos to be rejected (i.e., neighbor relationships will not even start to
form) if there is a mismatch in certain crucial OSPF capabilities. The OSPF
optional capabilities currently accepted include external routing capability and
TOS capability.
You need to map the binary bits to the supported options. For example, “3”
indicates both routing capability and TOS capability.
