    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


    mpls traffic-eng auto-tunnel meshmpls traffic-eng auto-tunnel mesh tunnel-num min num max numinterface auto-template interface-numtunnel destination access-list num

    tunnel destination access-list num

    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.

    In the above figure, the line
    Tunnel62000-62999 LR2 BACKUP


    corresponds to the following backup auto-tunnel configuration statements:

    In the above figure, the line
    Tunnel60000-60999 LR2 ACL-7 0 R,A2Z,LP,LDP,PATH1(NORTH),PBK10(dynamic) 7,7 #!


    corresponds to the following mesh group auto-tunnel configuration statements:
