An engineer is implementing MPLS OAM to monitor traffic within the MPLS domain. Which action must the engineer perform to prevent packets from being forwarded beyond the service provider domain when the LSP is down?

  1. Configure a private IP address as the destination address of the headend router of Cisco MPLS TE.
  2. Disable IP redirects only on outbound interfaces.
  3. Disable IP redirects on all ingress interfaces.
  4. Implement the destination address for the LSP echo request packet in the 127.x.y.z/8 network.

Answer(s): D



A network engineer has configured TE tunnels in the MPLS provider core. Which two steps ensure traffic traverse? (Choose two.)

  1. Static routes is the only option for directing traffic into a tunnel.
  2. ECMP between tunnels allows RSVP to function correctly.
  3. Forwarding adjacency features allows a tunnel to be Installed in the IGP table as a link.
  4. The IGP metric of a tunnel is configured to prefer a certain path
  5. A tunnel weight is configured in SPF database the same way as a native link.

Answer(s): C,D



An engineer is implementing a Cisco MPLS TE tunnel to improve the streaming experience for the clients of a video-on-demand server. Which action must the engineer perform to configure extended discovery to support the MPLS LDP session between the headend and tailend routers?

  1. Configure a targeted neighbor session.
  2. Configure an access list on the interface to permit TCP and UDP traffic.
  3. Configure a Cisco MPLS TE tunnel on both ends of the session.
  4. Configure the interface bandwidth to handle TCP and UDP traffic between the LDP peers.

Answer(s): A

An engineer implemented LDP protocol on the ISP network. The engineer must ensure that there are no packet loss issues when IGP and LDP protocols are not synchronized. Which configuring must the engineer implement so that the IGP routing protocol will wait until LDP convergence is completed?

  1. Disable IP CEF routers running LDP and enable LDP protocol.
  2. Configure MPLS LDP IGP synchronization on the network.
  3. Configure LDP sessions protection on the network.
  4. Disable MPLS LDP IGP synchronization on the network.

Answer(s): B
