Layer 2 Access Concentrator Chapter 5 Configuring the Layer 2 Tunnel Protocol Access Concentrator and Network Server Enabling Sessions with Different Domains to Share the Same Tunnel To enable sessions authorized with different domains to share the same tunnel, enter the following commands: Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 Command Purpose Router> enable Enters privileged EXEC mode. Router# config 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 Cisco 10000 series router and enters VPDN request-dialin group mode. Router(config-vpdn-req-in)# protocol 12tp Specifies the Layer 2 Tunnel Protocol. Router(config-vpdn-req-in)# domain domain-name Requests that PPP calls from the specified domain be tunneled. Note For multiple domains over the same tunnel, repeat this step to list all of the domains you want that tunnel to support. To configure the same domain over multiple tunnels, you must configure load balancing and sharing between the tunnels by using the loadsharing ip ip-address [limit session-limit] command in VPDN group configuration mode. Router(config-vpdn-req-in)# exit Returns to VPDN group configuration mode. Router(config-vpdn)# initiate-to ip ip-address [priority priority-number] Specifies the LNS IP address and optionally the priority of the IP address (1 is the highest). Verifying Tunnel Sharing Configuration on the LAC To verify tunnel sharing configuration on the LAC, enter the following command in privileged EXEC mode: Command Router# show running-config Purpose Displays the running configuration and allows you to check that you successfully enabled the tunnel sharing feature.
