05.The connection between routers B and C has been successfully tested. However, after rebooting router C, the administrator noticed the response time between networks 10.10.3.0 and 10.10.4.0 is slower. Ping between the two routers is successful. A trace route indicates three hops from router B to router C. What else can be done to troubleshoot the problem?
  • Ping router B S0/1 connection from router C.
  • Trace the connection between router B to router C S0/1.
  • Issue a show ip route command in router B to verify routing is enabled.
  • Issue a show ip interface brief command on router C.

  • Router# name Fontana
  • Router# hostname Fontana
  • Router(config)# name Fontana
  • Router(config)# hostname Fontana
