Specifying the source IP address for outgoing RADIUS packets
The source IP address of RADIUS packets that a NAS sends must match the IP address of the NAS
configured on the RADIUS server. A RADIUS server identifies a NAS by its IP address. Upon
receiving a RADIUS packet, a RADIUS server checks whether the source IP address of the packet is
the IP address of a managed NAS.
•
If it is the IP address of a managed NAS, the server processes the packet.
•
If it is not the IP address of a managed NAS, the server drops the packet.
The source address of outgoing RADIUS packets is typically the IP address of an egress interface on
the NAS to communicate with the RADIUS server. However, in some situations, you must change
the source IP address. For example, when VRRP is configured for stateful failover, configure the
virtual IP of the uplink VRRP group as the source address.
You can specify a source IP address for outgoing RADIUS packets in RADIUS scheme view or in
system view.
•
The IP address specified in RADIUS scheme view applies only to one RADIUS scheme.
•
The IP address specified in system view applies to all RADIUS schemes whose servers are in a
VPN or the public network.
Before sending a RADIUS packet, the NAS selects a source IP address in the following order:
1. The source IP address specified for the RADIUS scheme.
2. The source IP address specified in system view for the VPN or public network, depending on
where the RADIUS server resides.
3. The IP address of the outbound interface specified by the route.
To specify a source IP address for all RADIUS schemes in a VPN or the public network:
Step
1. Enter system view.
2. Specify a source IP address
for outgoing RADIUS
packets.
To specify a source IP address for a RADIUS scheme:
