Multicast Interface Configuration (igmp and dr)

Hello,


I would like some advice please on what the above should be set for.


I plan to roll pim-sparse-dense mode out over a large corporate network in London using Auto-RP very soon, and I plan to set the PIM DR manually to the HSRP active interface so that we can have unicase and multicast active on the same interface.


I am also going to set the ip pim query-interval to the same values as out HSRP values.


A typical config would be for a lan with two routers is :-


!

interface Vlan573

description Server Farm

ip address 40.253.73.251 255.255.255.0

ip pim sparse-dense

ip pim dr priority 110

ip pim query-interval 2

standby timers 2 6

standby priority 110 preempt

standby ip 30.253.73.253

!




Should I also change the IGMP timers to co-inside with the HSRP and PIM DR timers ?


ip igmp query-timeout <value>

ip igmp query-interval <value>



????????????????




Many thx indeed,

Ken
