<Sysname> system-view
[Sysname] radius client enable
radius nas-backup-ip
Use radius nas-backup-ip to specify a backup source IP address for outgoing RADIUS packets.
Use undo radius nas-backup-ip to restore the default.
Syntax
radius nas-backup-ip ip-address [ vpn-instance vpn-instance-name ]
undo radius nas-backup-ip
Default
A device is configured with no backup source IP address for outgoing RADIUS packets.

Default command level
2: System level
Parameters
ip-address: Backup source IP address for outgoing RADIUS packets. It must be the source IP address for
outgoing RADIUS packets that is configured on the backup device for stateful failover and cannot be
0.0.0.0, 255.255.255.255, a class D address, or a class E address.
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the backup source IP address
belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. With a VPN
specified, the command specifies a private-network backup source IP address. With no VPN specified,
the command specifies a public-network backup source IP address.
Usage guidelines
The following matrix shows the command and router compatibility:
Command 6602 HSR6602 6604/6608/6616
radius nas backup-ip Yes Yes No
With a backup source IP address configured for outgoing RADIUS packets, a device for stateful failover
sends this address to the RADIUS server if it is the active device. When the active device fails, the RADIUS
server can send unsolicited RADIUS packets to the backup device.
You can specify up to one public-network backup source IP address and 15 private-network backup
source IP addresses. A newly specified public-network backup source IP address overwrites the previous
one. Each VPN can have only one private-network backup source IP address specified at most. A
private-network backup source IP address newly specified for a VPN overwrites the previous one.
The setting configured by the nas-backup-ip command in RADIUS scheme view is only for the RADIUS
scheme, whereas that configured by the radius nas-backup-ip command in system view is for all RADIUS
schemes. The setting in RADIUS scheme view takes precedence.
