Configuring Groups to Support Routing Matrix Components

For easy maintenance of chassis in a routing matrix, you can add a configuration group for each Routing Engine in the T640 routing nodes and TX Matrix platform. The configuration groups added to the TX Matrix platform configuration offer a simple way to establish hostnames, management interfaces, and default routes. In the example below, groups re0 and re1 refer to the TX Matrix platform Routing Engines, while groups lcc0-re0 and lcc0-re1 refer to the Routing Engines on T640 routing node LCC0. To configure groups for the TX Matrix platform, include the re0 and re1 statements at the [edit groups] hierarchy level. To configure groups for the T640 routing nodes, include the lccnumber-re0 and lccnumber-re1 statements at the [edit groups] hierarchy level.

                }

            }

        }

    }

    re1 {

        system {

            host-name hostname-scc-re1;

            backup-router ip-address;

        }

        interfaces {

            fxp0 {

                unit 0 {

                    family inet {

                        address ip-address;

                    }

                }

            }

        }

    }

    lcc0-re0 {

        system {

            host-name hostname-lcc0-re0;

            backup-router ip-address;

        }

        interfaces {

            fxp0 {

                unit 0 {

                    family inet {

                        address ip-address;

                    }

                }

            }

        }

    }

    lcc0-re1 {

        system {

            host-name hostname-lcc0-re1;

            backup-router ip-address;

        }

        interfaces {

            fxp0 {

                unit 0 {

                    family inet {

                        address ip-address;

                    }

                }

            }

        }

    }

}

apply-groups [ re0 re1 lcc0-re0 lcc0-re1 ];

Note that apply groups can be nested. For example, any configuration statements that are common to lcc0-re0 and lcc0-re1 can be put into a separate group and then added as an apply group to the lcc0-re0 and lcc0-re1 groups, which in turn are applied to the main configuration.

For more information about configuration groups, see the JUNOS CLI User Guide.
