Hi

I have a question regarding the election of the LAN router which is supposed
to send the queries for multicast accesses.

In chapter 8, page 302, IGMPv2 querier election, it is mentioned that the
router with the lowest IP address is elected as multicast querier. In
Chapter 9, page 336, it is mentioned that the DR (designated Router) elected
is the one with the highest IP address. "The DR is responsible for sending
IGMP host-query messages to all host on the LAN".

Could you please help me understand the differences between the two above
cases, because for me, routers seem to have the exactly same role but are
elected an opposite way...

thanks

DJ
