VRF support for Telnet

AN overview of VRF support for Telnet and example commands.

You can configure Telnet on any routing instance. If you configure Telnet without specifying a routing instance, the default routing instance is used.

When you configure Telnet service in a routing instance, the external user can connect to the vRouter through a Telnet session by using the configuration parameters for that instance.

The Telnet service can be started with parameters that are specified in the configuration. If parameters are not specified, Telnet service starts on the default port (port 23).

The following example shows how to configure Telnet for the default routing instance.

vyatta@R1# set service telnet listen-address 42.42.42.42
vyatta@R1# set service telnet port 1234
vyatta@R1# commit
vyatta@R1# run show configuration
service {
        telnet {
                listen-address 42.42.42.42
                port 1234
        }
}

The following example shows the same configuration sequence for the BLUE routing instance.

vyatta@R1# set routing routing-instance BLUE service telnet listen-address 42.42.42.42
vyatta@R1# set routing routing-instance BLUE service telnet port 1234
vyatta@R1# commit
vyatta@R1# run show configuration
routing {
        routing-instance BLUE {
                service {
                        telnet {
                                listen-address 42.42.42.42
                                port 1234
                        }
                }
        }
}
