Restore topology

The following configuration restores the topology to a certain state, setting the stage for the next chapter.

• On router P2, change the metric on the P2-P3 link back to 10 from 100:

  P2

  router isis IGP
  interface GigabitEthernet0/0/0/0
    address-family ipv4 unicast
     metric 10

• On router P7, bring up the links toward P2, P3, and P4 back in IS-IS to activate them in the current topology:

  P7

  router isis IGP
  interface GigabitEthernet0/0/0/1
    no shutdown
  !
  interface GigabitEthernet0/0/0/3
    no shutdown
  !
  interface GigabitEthernet0/0/0/4
    no shutdown

This concludes the microloop avoidance lab, and the lab summary follows.
