KISS - keep things as simple as possible... OSPF is an open protocol, and it's very simple in case if you have not 500 routers and 1000 flapping routes in the network - what do you searching the headache for? Multicast routing depends more from the options you have from the hardware vendor - choose the simplest and more standard method and turn it on... PS. From my lectures to the students, quote: --- The most complex routing method is STATIC - it's easy to implement (for the HW vendor) but most difficult to configure. The simplest routing is just dynamic routing in the plain schema (for example, 'router ospf 1/network 0.0.0.0 255.255.255.255 - just 2 lines for the CISCO, compare to the static' - may be it can argue someone do not use the static at all -:) --- On Mon, 13 Sep 1999, Jack Crowder wrote:

I was wondering if I could talk with someone who has recently implemented IS-IS. I'm attempting to move a small NSP away from static routing and based on their topology - OSPF would have to be configured all in Area 0.

Since the technology provided by this NSP to their customers will include multicast services (video specifically), I thought that I should consider IS-IS while the slate is relatively clean.

If there is someone who has implemented this routing on their network that I could ask a few questions of (practical experience), I would appreciate it.
