multicast redundancy

[pgionas]

Hi

can someone point me to the right documents.....

i am looking for guidelines on how to design redundancy in a multicast routing environment for the LAN. I can use VRRP/HSRP for redundancy for unicast packets, but how do i ensure mcast routing redundancy ?

is it as simple as having multiple mcast routers per VLAN who will be able to forward any mcast packets across the VLAN....how will IGMP querying work in this scenario ?

Here is a good starting point for setting up multicast routing/redundancy.
