The following table describes the fields in the output for the show ipv6 default-routers command.


Parameter	Description
net address	Shows the IPv6 router address received from a valid router advertisement.
VLAN `<1–4059>`	Shows the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. If you enable VRF scaling and SPBM mode, the system also reserves VLAN IDs 3500 to 3999. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1.
LIFETIME	Shows the value placed in the router lifetime field of router advertisements. This value must be either 0 or between 4 and 9000. A value of zero indicates that the system is not a default router. The default is 1800.
IS ACTIVE	Shows if the default router is active or inactive.
