How to Supress Hello packets on an interface enabled for OSPF

[jmacfarlane]

As I understand it, enabling an interface to join an area with the

NETWORK command, also causes Hello packets to be sent out the

interface. But if its a stub network, and you want it advertised, but

there is no need for Hello packets to be sent out the interface, how do

you suppress them?

The passive-interface command seems to be discouraged in OSPF, since

there is far more granular control over which interfaces are affected

by the network command.

The "redistribute connected subnets" could be used after entering the

network command with a very restrictive mask that advertises only

non-stub network interface(s). But that seems to open a whole new can

of redristribute issues.

This is simple to do, right?

I don't why passive interface would be discouraged in OSPF--I've seen it used a lot in the networks I've worked on. In fact, with the advent of the passive-interface default command, it's much easier use passive interface in all the routing protocols.

The general rule of thumb is, if you want the routes to be internals, then use passive interface. If you want them to be externals, then use redistribute connected. You can filter the routes you pull in through redistribute connected using a route map. You can control which interfaces are pulled in through passive using the network statement.
