Chapter 5 Configuring the Layer 2 Tunnel Protocol Access Concentrator and Network Server L2TP Network Server LNS Configuration to Support RADIUS Tunnel Authentication The following example is an LNS configuration that supports RADIUS tunnel authentication. In this configuration, a RADIUS server group is defined by using the aaa group server radius VPDN-Group command. The aaa authorization network mymethodlist group VPDN-Group command queries RADIUS for network authorization. aaa group server radius VPDN-Group server 64.102.48.91 auth-port 1645 acct-port 1646 aaa authorization network mymethodlist group VPDN-Group vpdn tunnel authorization network mymethodlist vpdn tunnel authorization virtual-template 10 RADIUS Configuration to Support Tunnel Authentication The following example is a RADIUS configuration that allows the LNS to terminate L2TP tunnels from a LAC. In this configuration, VirtualTemplate10 is used to clone a VAI on the LNS. myLACname Password = "cisco" Service-Type = Outbound, Tunnel-Type = :0:l@TP, Tunnel-Medium-Type = :o:IP, Tunnel-Client-Auth-ID = :0:"myLACname", Tunnel-Password = :0:"mytunnelpassword", Cisco:Cisco-Avpair = "vpdn:vpdn-vtemplate=10" Note For additional authentication examples, see the "Configuring Authentication" chapter in the Cisco IOS Security Configure Guide, Release 12.2. Monitoring and Maintaining LNS To monitor and maintain the features configured on the LNS, enter the following commands in privileged EXEC mode: Command Router# show accounting Router# show interfaces virtual-access number [configuration] Router# show ip route vrf vrf-name Router# show radius statistics Router# show vpdn Router# show vpdn session Router# show vpdn session all username username Purpose Displays accounting records for users currently logged in. Displays active accountable events on the network and helps collect information in the event of a data loss on the accounting server. Displays status, traffic data, and configuration information about the virtual access interface you specify. Displays the IP routing table associated with a VRF. Displays the RADIUS statistics for accounting and authentication packets. Displays all tunnel and session information for all active sessions and tunnels. Displays information about active L2TP sessions in a virtual private dialup network (VPDN). Displays statistics about all active L2TP tunnels for the username you specify.
