Step 2: Apply the New Group

Action

To apply the re0 group to maintain a single configuration file for both Routing Engines, follow these steps:

1. In configuration mode, go to the top hierarchy level and include the following statement:

user@host# [edit]

user@host# set apply-groups group-name

For example:

user@host# [edit]

user@host# set apply-groups re0

2. Verify the configuration:

user@host# show

groups {

    re0 {

        system {

            host-name foo-re0;

        }

        interfaces {

            fxp0 {

                unit 0 {

                    family inet {

                        address 1.1.1.1/24;

                    }

                }

            }

        }

    }

    re1 {

        system {

            host-name foo-re1;

        }

        interfaces {

            fxp0 {

                unit 0 {

                    family inet {

                        address 1.1.1.2/24;

                    }

                }

            }

        }

    }

}

apply-groups [ re0 re1 ];

3. Commit the configuration:

user@host# commit

What It Means

The sample output shows that each group, re0 and re1, has its own IP address that is used for each Routing Engine to maintain a single configuration file.
