Adding T1 Interfaces to a RIP Group

If you want to enable the Routing Information Protocol (RIP) on an interface, you must make changes at both the [edit interfaces] and [edit protocols rip] hierarchy levels. This example shows you how to use commit scripts to decrease the amount of manual configuration.

This example adds every T1 interface configured at the [edit interfaces] hierarchy level to the [edit protocols rip group test] hierarchy level. This example includes no error, warning, or system log messages. The changes to the configuration are made silently.

Testing ex-rip-t1.xsl

To test the example in this section, perform the following steps:

From Adding T1 Interfaces to a RIP Group, copy the Extensible Stylesheet Language Transformations (XSLT) or SLAX script into a text file, and name the file ex-rip-t1.xsl. Copy the ex-rip-t1.xsl file to the /var/db/scripts/commit directory on your routing platform.

Select the following configuration, and press Ctrl+c to copy it to the clipboard. If you are using the SLAX version of the script, change the filename to filename.slax.



system {
    scripts {
        commit {
            file ex-rip-t1.xsl;
        }
    }
}
interfaces {
    t1-0/0/0 {
        unit 0 {
            family iso;
        }
    }
    t1-0/0/1 {
        unit 0 {
            family iso;
        }
    }
    t1-0/0/2 {
        unit 0 {
            family iso;
        }
    }
    t1-0/0/3 {
        unit 0 {
            family iso;
        }
    }
    t1-0/1/0 {
        unit 0 {
            family iso;
        }
    }
    t1-0/1/1 {
        unit 0 {
            family iso;
        }
    }
    t1-0/1/2 {
        unit 0 {
            family iso;
        }
    }
    t1-0/1/3 {
        unit 0 {
            family iso;
        }
    }
}

Merge the configuration into your routing platform configuration by issuing the load merge terminal configuration mode command:[edit] user@host# load merge terminal [Type ^D at a new line to end input] > Paste the contents of the clipboard here<
1. At the prompt, paste the contents of the clipboard using the mouse and the paste icon.
2. Press Enter.
3. Press Ctrl+d.
Issue the commit command. When you issue the show protocols rip group test configuration mode command, the following output appears:[edit] user@host# show protocols rip group test neighbor t1-0/0/0.0; neighbor t1-0/0/1.0; neighbor t1-0/0/2.0; neighbor t1-0/0/3.0; neighbor t1-0/1/0.0; neighbor t1-0/1/1.0; neighbor t1-0/1/2.0; neighbor t1-0/1/3.0;
