Table 3-57: show ipv6 ospf virtual-links output details
Field
Description
Virtual Link
Virtual link name, the router ID to which it is connected, and the state of the link.
Transit area
Transit area ID, the interface it uses, and its instance ID – an Instance ID should default to 0. It is only necessary to assign a value other than 0 on those links that will contain multiple separate communities of OSPF routers.
Local address
The local IPV6 address and subnet mask.
Remote address
The remote IPv6 address and subnet mask.
Transmit Delay
The delay, in seconds, between link-state transmits. This value must be the same for all nodes on the network. The range is 1 to 65535. The default is 1. The state is point-to-point.
Timer intervals configured
The configured values in seconds of the following timers: Hello, Dead, Wait, Retransmit.
Hello due in
A countdown timer that indicates when the next Hello packet should arrive.
Adjacency State
Whether the adjacency state is either up or down.
