what default length is used for the ospf dead interval?

The default setting of the ospf dead interval is 60 seconds. For a non-compliant node, the default is set to 90 seconds. A compliant node sets the default to 30 seconds.

So I read somewhere that the default is 30 seconds. The reason I read that is because that’s exactly how it appears when I try to ping an ospf dead address. It takes 30 seconds for the message to be acknowledged and then my computer thinks it has a minute to react to the message.

This is very likely because of the default setting of the ospf dead interval. The ospf protocol is designed to have it ping messages at a particular interval. So if a node thinks its dead, then its not dead and its unable to send any more packets. For me, this means that the IPs I am trying to ping are probably still alive, because they should still be able to send and receive packets at a given interval.

Well, I guess I was asking what the default setting actually is. It’s probably not a good idea to ask too much of the developers, because they are probably like me and just like me, they don’t want you to know the answer too well.

Yeah, I was just wondering if there’s a default length.

There are a couple of ways to view a dead interval.

The first is to set the IPs you are trying to ping to the IP of your host, and in this case the IP of the host you are trying to ping. You can set the IP to some arbitrary value, but its a good idea to start with a default length. The default IP of the host you are trying to send to is the one you have to ping. It’s only if you have a host you can send a frame based IP.

The other way to view your IPs is to set the IPs as the IPs you are trying to ping. This is called ping-to-ip and it is the most complicated of all the dead interval methods. The IP of the host you are trying to ping is the IP of your host. The IP of your host is the IP of both the host you are trying to ping and the host your are trying to send a frame to.

So what does this all mean? It means that defaulting to 1.5 seconds as the dead interval means you are using a ping with a default of 1.5 seconds. If you have a 1.5 second ping, you will get a response from your host, even if they are not online. If you are trying to ping a host with a default of 1.

You can also use the default to be used for the purpose of a TTL. If your ping is not timed out, your host will still respond to the frame, even if you are not online, even if your host is not online. This is great for routers, and it is great for mobile devices, but not so great if you are trying to ping a host for a TTL of 1 second.
