MPLS label values must be an integer from 16 to 1048575.
Important:
This option is available only when nexthop-forwarding gateway is also configured with
keyword.
Configures the next hop IP address for this NAS IP address.
must be an IPv4 address or an IPv6 address in standard format.
Configures VLAN ID to be associated with the next-hop IP address.
must be an integer from 1 through 4094.
Usage
This is necessary for NetWare Access Server usage such as the system must be identified to the NAS.
The system supports the concept of the active nas-ip-address. The active nas-ip-address is defined as the
current source ip address for RADIUS messages being used by the system. This is the content of the nas-ip-
address attribute in each RADIUS message.
The system will always have exactly one active nas-ip-address. The active nas-ip-address will start as the
primary nas-ip-address. However, the active nas-ip-address may switch from the primary to the backup, or
the backup to the primary. The following events will occur when the active nas-ip-address is switched:

All current in-process RADIUS accounting messages from the entire system are cancelled. The
accounting message is re-sent, with retries preserved, using the ne w active nas-ip-address. Acct-
Delay-Time, however, is updated to reflect the time that has occurred since the accounting event.
The value of Event-Timestamp is preserved.

value of Event-Timestamp is preserved.
All subsequent in-process RADIUS requests uses the new active nas-ip-address.
The system uses a revertive algorithm when transitioning active NAS IP addresses as described below:
If the configured primary nas-ip-address transitions from UP to DOWN, and the backup nas-ip-address
is UP, then the active nas-ip-address switches from the primary to the backup nas-ip-address
If the backup nas-ip-address is active, and the primary nas-ip-address transitions from DOWN to UP,
then the active nas-ip-address switches from the backup to the primary nas-ip-address
