721.1RouteAbout has 4 Multicast Routing Protocols !MARVIN::HARTTony Hart, InterNetworking Prod. Eng. GroupFri Jan 31 1997 12:4615
RouteAbout V2.0 supports...
	MOSPF
	DVMRP (version V1.0)
	PIM Dense Mode
	PIM Sparse Mode
	IGMP V1

DECNIS supports...
	PIM Dense Mode
	IGMP V1

Note that since the PIM protocol is still evolving, you are unlikely to have
verndor interoperability so if you need interoperability use MOSPF or DVMRP.

721.2Multicast forwarding rate is limitedMARVIN::SHANDMike ShandMon Feb 03 1997 08:335
I'm a little concerned by the mention of "video multicast". Don't expect
particularly good performance, especially on DECNIS, where it is all done by the
MPC).

721.3how about VN with routing for thisNETRIX::"[email protected]"eric ganTue Mar 11 1997 06:109
Hi,

How about VN products with V2 routing software to do video multicast?
Maybe the performance is better than DECNIS or same with it?


thanks in advance,
eric

721.4post VNS-V2 releaseMARVIN::HARTTony Hart, InterNetworking Prod. Eng. GroupTue Mar 11 1997 08:197
IP multicast on the VNSwitch is scheduled for a release after VNS-V2.  The
performance should be much better than either DECNIS or RouteAbout/DECswitch,
the aim is to do the forwarding in the VNS fast-path processor.

VNS V2 won't support IP multicast routing.

721.5patch?NETRIX::"eric gan@bejvc"ericganWed Mar 12 1997 08:386
Oho, bad news!
But can I get a patch for IP multicast in V2? Since the customer has
the additional request!

721.6There is no patchMARVIN::HARTTony Hart, InterNetworking Prod. Eng. GroupWed Mar 12 1997 09:274
There isn't a patch for IP multicast.  Unfortunately you will have to wait for
vns-V3 or later.  Until then only DECswitch, RouteAbout and DECNIS support
IP multicast routing.

Alice Hassey is the Product Manager for VNSwitch, she should be able to answer
your question.
