  Explanation

  OSPF adjacency is established when two OSPF routers have matching interface parameters. This includes the OSPF router ID, network address, area ID, and other OSPF-specific configurations such as MTU size and network type. For example, the configuration commands provided in the image description suggest setting the OSPF router ID, network address with a wildcard mask, and specifying the OSPF area. Additionally, the interface is set to a point-to-point network type with a specific MTU size, which is important for OSPF adjacency as mismatched MTU sizes can prevent OSPF neighbors from forming an adjacency.

• Question 22:

  Refer to the exhibit.

  

  A Cisco engineer is implementing gRPC dial-out on an ASR. Receiver 192.168.1.1 will be assigned one of the subscriptions, and it will manage the ASR.

  Which command is needed to complete the router configuration?

  A. protocol tcp
  B. protocol any
  C. protocol grpc
  D. protocol all
  C. protocol grpc

  ---

  Explanation

  In this scenario, gRPC dial-out mode is being used for telemetry. The receiver with IP address 192.168.1.1 will be assigned one of the subscriptions and will manage the ASR. To configure this, the router needs to use the protocol tcp command. This ensures that telemetry data is streamed out over a TCP connection to the specified receiver. Other options (A, B, and D) are not relevant for this specific use case.

  Tasks

  Configure the BGP routing protocol for R1 and R2 according to the topology to achieve these goals:

  1. Configure EBGP neighbor adjacency for the IPv4 and IPv6 address family between R1 and R2 using Loopback0 IPv4 and IPv6 addresses. All BGP updates must come from the Loopback0 interface as the source. Do not use IGP routing protocols to complete this task.

  2. Configure MD5 Authentication for the EBGP adjacency between R1 and R2. The password is clear text C1sc0!.

  Which show command should be implemented to display per-interface statistics about uRPF drops and suppressed drops?

  A. show ip traffic
  B. showip interface
  C. show cef interface
  D. show ip interface brief
  C. show cef interface

  ---

  Explanation

  The "show cef interface" command is used to display per-interface statistics about Unicast Reverse Path Forwarding (uRPF) drops and suppressed drops. uRPF is a feature that helps to mitigate problems caused by IP address spoofing, and the "show cef interface" command provides detailed information on the interfaces where uRPF is applied, including drop statistics.
