The test procedure with the ping –r command (see
The source (Device A) sends an ICMP echo request with the RR option being empty to the
1.
destination (Device C).
The intermediate device (Device B) adds the IP address of its outbound interface (1.1.2.1) to the RR
2.
option of the ICMP echo request, and forwards the packet.
Upon receiving the request, the destination device copies the RR option in the request and adds the
3.
IP address of its outbound interface (1.1.2.2) to the RR option. Then the destination device sends
an ICMP echo reply.
The intermediate device adds the IP address of its outbound interface (1.1.1.2) to the RR option in
4.
the ICMP echo reply, and then forwards the reply.
Upon receiving the reply, the source device adds the IP address of its inbound interface (1.1.1.1)
5.
to the RR option. Finally, you can get detailed information about routes from Device A to Device C:
1.1.1.1 <-> {1.1.1.2; 1.1.2.1} <-> 1.1.2.2.

Tracert

Tracert (also called "Traceroute") enables you to get the IP addresses of Layer 3 devices in the path to a
specific destination. You can use tracert to test network connectivity and identify failed nodes.
