Ping utility for testing CE device connectivity

Junos OS reachability to the customer endpoint can be achieved from the service endpoint in a network. This feature is supported in a virtual private LAN service (VPLS), hierarchical VPLS (H-VPLS), and Ethernet VPN (EVPN) network. It is based on the LSP ping infrastructure, where the ping utility is extended to use the CE device IP address as the target host and the PE device loopback address as the source for a specific VPLS or EVPN routing instance. To implement this feature, issue the ping ce-ip destination-ip-address instance routing-instance-name source-ip source-ip-address command on a PE device. Based on the configured routing instance type, the command output displays the connectivity information of the CE device.
