Restrictions for Configuring RADIUS VPN Support

When configuring RADIUS VPN support on the SBC, note that if multiple RADIUS servers have been defined, all of these RADIUS servers must be defined within the same VRF. This feature cannot be implemented if the RADIUS servers are defined in separate VRFs.

Information About RADIUS VPN Support

The SBC allows users to specify which VPN to use for configuring the AAA IPv4 addresses. All the servers that the SBC accesses must be within the VPN configured on the AAA control address CLI. The RADIUS messages are then sent to the IPv4 address configured with the VPN.

---

Note If a VPN is not configured, the global address space is used as the default address.

How to Configure RADIUS VPN Support

This section contains the steps for configuring the SBC with RADIUS VPN Support:

SUMMARY STEPS

1. configure

2. sbc service-name

3. sbe

4. control address aaa ipv4 ipv4_address vrf vrf_name

5. commit

6. exit

DETAILED STEPS

	Command or Action	Purpose
Step 1	configure Example: RP/0/0/CPU0:router# configure	Enables the global configuration mode.
Step 2	sbc service-name Example: RP/0/0/CPU0:router(config)# sbc mysbc	Enters the mode of an SBC service. Use the service-name argument to define the name of the SBC.
Step 3	sbe Example: RP/0/0/CPU0:router(config-sbc)# sbe	Enters the mode of the signaling border element (SBE) function of the SBC.
Step 4	control address aaa ipv4 ipv4_address vrf vrf-name Example: RP/0/0/CPU0:router(config-sbc-sbe)# control address aaa ipv4 10.0.0.0 vrf vpn3	Configures the specified AAA control address within the VRF. •Use the ipv4_address argument to specify the local address of the SBC RADIUS client. •Use the vrf-name argument to specify the name of the VRF to use for the RADIUS client.
Step 5	commit Example: RP/0/0/CPU0:router(config-sbc-sbe-adj-h323)# commit	Saves configuration changes. Use the commit command to save the configuration changes to the running configuration file and remain within the configuration session.
Step 6	exit Example: RP/0/0/CPU0:router(config-sbc-sbe)# exit	Exits the SBE mode.
