My server admin hasn't used Norton Ghost in awhile and he went to use it the other day and it didn't work. I asked him try pushing it out by unicast and it worked. I enable IP Multicast-routing on my core switch but it still doesn't seem to be working. I know there are tons of pages of documentation out there, but i was wondering if anyone had any suggestions. It seems like by enabling that IP Multicast-routing the core switch should be able to just forward it out to the appropriate vlan.
800, u might be better off using pim dense mode then.
anyways, for RP "ip pim rp-address x.x.x.x" x.x.x.x is a loopback for example.
ur RP should be located close to the source. it will set the source of multicast forwarding tree.
also, if the application needs a good uptime, redundant RP is best.
I still think with 800 trees, dense mode is best and no RP is needed.
to be sure it work, do "so ip mroute count" u will see if packets are forwarded.
