  This module describes how to configure an IP Service Level Agreements (SLAs) Internet Control Message Protocol (ICMP) Echo operation to monitor end-to-end response time between a Cisco router and devices using IPv4 or IPv6. ICMP Echo is useful for troubleshooting network connectivity issues. This module also demonstrates how the results of the ICMP Echo operation can be displayed and analyzed to determine how the network IP connections are performing. ICMP Echo Operation The ICMP Echo operation measures end-to-end response time between a Cisco router and any devices using IP. Response time is computed by measuring the time taken between sending an ICMP Echo request message to the destination and receiving an ICMP Echo reply. In the figure below ping is used by the ICMP Echo operation to measure the response time between the source IP SLAs device and the destination IP device. Many customers use IP SLAs ICMP-based operations, in-house ping testing, or ping-based dedicated probes for response time measurements.

  

  The IP SLAs ICMP Echo operation conforms to the same IETF specifications for ICMP ping testing and the two methods result in the same response times. Configuring a Basic ICMP Echo Operation on the Source Device SUMMARY STEPS

• Question 999:

  If all OSPF routers in a single area are configured with the same priority value, what value does a router use for the OSPF router ID in the absence of a loopback interface?

  A. the IP address of the first Fast Ethernet interface
  B. the IP address of the console management interface
  C. the highest IP address among its active interfaces
  D. the lowest IP address among its active interfaces
  E. the priority value until a loopback interface is configured
  C. the highest IP address among its active interfaces

  ---

  Explanation: Ordinarily the loopback interface would be selected as the router ID. In the event that no loopback interface is configured, the router ID will be the first active interface that comes up on the router. If that particular interface has more then one IP address, then the highest address will be selected as the Router ID.

• Question 1000:

  Which command displays the number of times that an individual router translated an inside address to an outside address?

  A. show ip protocol
  B. show ip nat translation
  C. show counters
  D. show iproute
  E. show ip nat statistics
  B. show ip nat translation
