The advantage is that you can turn up a customer the same day compared to having to schedule some maintence to make the network multicast enabled. Making all your bgp sessions do unicast+multicast is a trivial configuration change and does not cause any extra instability. Then you can turn on/off pim to the edge where the customer is attached as needed. - Jared On Sat, Jun 09, 2001 at 10:43:54PM -0400, Deepak Jain wrote:
I think I should have been more clear.
When multicast enabling a network, am I wrong in assuming that the routers will only multicast to their direct, end-user connections and peers (like an access router will only offer streams to its direct connections)? I am trying to figure out what advantages multicast-enabling a backbone has when the majority of customers are not multicast-peers of their upstream routers.

(almost) any verio customer can receive multicast. It is available upon request. Let me know if you are a verio customer and require assistance getting multicast.

verio and l3 are both multicast enabled... I don't know the extent to which it's available as a customer...

Don't know why I came across this, but I found a document on
Sprintlink's
site that says their entire backbone is multicast enabled, and they also peer with the MBONE for multicast traffic. They charge no fee for dedicated customers to be multicast-enabled.
Are any other major networks doing this? Or have I been living under a rock and _everyone_ is doing this now?
