Question
Refer to the exhibit. OSPF is running in the core, with MPLS configured on all links. A Cisco MPLS TE tunnel is configured with R1 as the headend and R4 as the tail-end router. As traffic on the network increases, the network engineering team is concerned about identifying failures between the tunnel endpoints. Which action should the engineering team take that will allow them to identify and locate any faults in the path?
Exhibit
Options
- AImplement NetFlow to determine whether traffic is traversing the egress interfaces as expected.
- BImplement an ICMP ping utility to send periodic test packets and identify the failure location.
- CImplement RSVP to determine whether bandwidth is properly allocated along the path.
- DImplement MPLS OAM with traceroute to follow the path and determine where packets are failing.
