[c-nsp] Interdomain Multicast Routing

[Mike Louis]

This has been a  confusing subject for me. If you enabled msdp between 2 pim sm domains and enabled mc routing on the intermediate bgp routers while using normal non-mbgp routing wouldn't mc still work? Why would you want to use mbgp unless you wanted mc routes to take a different path than unicast routes? Do most sp these days support mc in their networks for customers?

Thanks

mike

Hi,

The combination you've described has been working for many years,
very well tested, supported by all major vendors.
PIM (bidir as well) is used for intradomain  multicast routing independently
of interdomain multicast (MSDP/MBGP).
Cisco does support PIM Bidir

Cheers,
Jeff
