Importing Cisco Auto-Tunnel Information from Router Configuration Files


To import the router configuration files, select File>Import Data and follow the Import Network Wizard. Alternatively, you may run the getipconf program in text mode. See Router Data Extraction Overview for more detailed information. The following table lists those mesh group auto-tunnel and backup auto-tunnel related statements that are parsed during configuration import:

mesh group auto-tunnel statements

tunnel destination access-list num

mesh group auto-tunnel statements

mpls traffic-eng auto-tunnel mesh

mpls traffic-eng auto-tunnel mesh tunnel-num min num max num

interface auto-template interface-num

tunnel destination access-list num

Table 1: Cisco auto-tunnel statements parsed during configuration import

backup auto-tunnel statements

mpls traffic-eng auto-tunnel backup

mpls traffic-eng auto-tunnel backup nhop-only

mpls traffic-eng auto-tunnel backup tunnel-num [min num] [max num]

mpls traffic-eng auto-tunnel backup config unnumbered-interface interface

Once all of the options in the different tabs of Import Network Wizard have been selected, click Next> to begin importing the router config files. As you reach the end of configuration import, you will be prompted with a dialog box asking if you want to "Generate auto tunnels from atconfig file?", as shown in the following figure. If you wish the tool to generate auto-tunnels, then click on Yes.

The atconfig files store the auto-tunnels information parsed during configuration import. The following figure shows an atconfig file that was created during configuration import for a network that has both mesh group and backup auto-tunnels configured.
