Ari And Tobbe,
Will your update of BOM 0 include all this OSC modules for UNI sites and the extra OSC for
Malmö and Rätan?

Ämne: Re: Sunet Adva DCN
I created 200 ospf routers in juniper platform, 100 in each mx480 with p2p links inbetween
and a /32 loopback.
I would like to add them to the Adva lab to see what will happen.

Thanks Magnus, good work!
We should not forget new OSC to all active Uni sites that we decided on in our initial
design meeting. This will add to the total number of ospf speaking nodes.
Cheers
Björn
