  9. Just like HSRP, VRRP has the option of allowing the gateway to use the BIA or a statically configured address as the MAC address for VRRP groups. True or false?
  10. Which command can you use to configure a GLBP group “up” address on a router interface?

Section 48 Answers

  6. The HSRP priority parameter.
  7. It modifies HSRP priority based on interface status.
  8. The standby x ip y command.
  9. False.
  10. The glbp x ip y command.

Section 48 Lab – OSPF



Connect two routers together with a serial or crossover cable:

  1. Add IP addresses to the routers and a Loopback interface on Router A and Router B,
    according to the diagram
  2. Ping between Router A and Router B to test the serial line (remember clock rates)
  3. Configure OSPF on both routers
  4. Ensure that you add all the correct wildcard masks
  5. Double-check the WAN wildcard mask and subnet: it ISN’T!!
  6. Put all networks into an area, but put into Area 1 and into Area 2
  7. Check the routing table
  8. Check the router ID for each router
  9. How would you change the router ID for each router?

Solution Hints and Commands

  • Use the router ospf x command to enter OSPF Configuration mode
  • Use the network x.x.x.x y.y.y.y area z command to configure a network in an area
  • Use the show ip route command to view the routing table
  • Use the router-id x.x.x.x command to change the OSPF router ID under the OSPF Process Configuration mode
