Re: [j-nsp] OSPF default problem

As far as the router id, I went back to basics and looked in my junoscookbook and didn't skip a beat when I first set this up and it didn'twork. I just added in all of the steps it suggested, really nothingof consequence.

So, 10.0.0.0/24 is the network devices and 10.0.1.0/24 is themachines. That's why I have a /23 on that interface. Funny part isthat particular switch with 10.0.0.2 on it locally can hit theinternet and 10.0.0.1. No other device can nor can I ping 10.0.0.1with any other source on the local switch.

that looks about right, assuming that 10.0.0.31 is your ex4200 (out of
curiosity, why do you manually set the router id? I usually just use a
"preferred" lo0 address).

Ah, I think I see it now.

10.0.0.0/23 is your transfer between 10.0.0.1 and 10.0.0.2, yes? So

10.0.0.1 will ARP for all the router loopbacks on the connectionbetween

itself and the Ex4200 and will never route the packets toward the EX..
