Layer 2 Access Concentrator Chapter 5 Configuring the Layer 2 Tunnel Protocol Access Concentrator and Network Server Step 5 Step 6 Step 7 Step 8 Step 9 Command Router(config)# radius-server attribute 44 include-in-access-req vrf vrf-name Router(config)# radius-server domain-stripping vrf vrf-name Router(config)# radius-server attribute list list-name Router(config)# radius-server key string Router(config)# radius-server vsa send authentication Purpose Sends RADIUS attribute 44 (Accounting Session ID) in access request packets before user authentication (including requests for preauthentication). (Optional) Enables VRF-aware domain-stripping. The vrf vrf-name argument specifies the per VRF configuration. Defines the list name given to the set of attributes defined using the attribute command. Specifies the authentication and encryption key for all RADIUS communications between the router and the RADIUS daemon. Configures the LAC to recognize and use vendor-specific attributes. Example 5-4 Configuring Communication with the RADIUS Server ! aaa new-model aaa authorization network default local group radius ! radius-server host 10.16.9.9 auth-port 1645 acct-port 1646 radius-server attribute 44 include-in-access-req vrf vrf1 radius-server key MyKey radius-server vsa send authentication Verifying Communication with the RADIUS Server To verify that you successfully configured the LAC to communicate properly with the RADIUS server for tunnel service authorization, enter the show running-config command in privileged EXEC mode. Configuring Sessions Per Tunnel Limiting on the LAC To limit the number of sessions per tunnel without using a RADIUS server, enter the following commands. Note You can configure the LAC or the RADIUS server to limit the number of sessions per tunnel. For information on using the RADIUS server for sessions per tunnel limiting, see the "Configuring Sessions Per Tunnel Limiting in the RADIUS Service Profile" section on page 5-16. Step 1 Step 2 Step 3 Step 4 Step 5 Command Purpose Router> enable Enters privileged EXEC mode. Router# configure terminal Enters global configuration mode. Router(config)# vpdn-group group-name Defines a local group name for which you can assign other VPDN variables. Enters VPDN group configuration mode. Router(config-vpdn)# request-dialin Enables the LAC to request L2TP tunnels to the LNS and enters VPDN request-dialin group mode. Router(config-vpdn-req-in)# protocol 12tp Specifies the Layer 2 Tunnel Protocol. 5-12 Cisco 10000 Series Router Software Configuration Guide OL-2226-23
