How do you disable ospf updates

The command suppresses hello packets and hence neighbor relationships. The passive interface Command With EIGRP running on a network, the passive - interface command stops both outgoing and incoming routing updates, since the effect of the command causes the router to stop sending and receiving hello packets over an interface.

This is the output of the show ip eigrp neighbors. To return to the default, use the no form of this command. What is default information originate? What is passive interface in Cisco? Passive Interfaces. What factors are used to calculate the OSPF cost? OSPF uses a reference bandwidth of Mbps for cost calculation. The formula to calculate the cost is reference bandwidth divided by interface bandwidth.

Any interfaces that aren't explicitly included by a network statement will not take part in OSPF. On the other hand, sometimes a router can have a large number of interfaces, and you want all but one or two of them to take part in OSPF. In this case, it is more convenient to use passive interface commands. To see the effect of this command, we'll look at a network both with and without the passive interface configured.

Here is the neighbor list before configuring any passive interfaces:. Then, after making the Ethernet0 interface passive, the router drops all of the neighbor relationships on this interface. We are left with only one neighbor:.

Of course, this also affects any routes that point to neighboring routers through this interface. Configure the Interval Between Hello Packets. Restore the Default Value for Interface Cost. Testing Authentication Topology Example. Configure Simple Password Authentication.
