Enable passive interfaces
A passive interface is one that does not send or receive routing information. Enabling passive interface
suppresses routing updates on an interface. Although the passive interface will neither send nor receive
routing updates, the network on that interface will still be included in OSPF updates sent via other
interfaces.
