Exam 350-401 topic 1 question 489 discussion

IGMPV1 is highest. IGMPV2 uses lowest per https://www.ciscopress.com/articles/article.asp?p=2738463&seqNum=6

If there are multiple routers on a subnet; - the DR is the device with the highest IP address and the querier is the device with the lowest IP address.

lowest interface IP

Query messages are used to elect the IGMP querier as follows: 1. When IGMPv2 devices start, they each multicast a general query message to the allsystems grou address of 224.0.0.1 with their interface address in the source IP address field of the message. 2. When an IGMPv2 device receives a general query message, the device compares the source IP address in the message with its own interface address. The device with the lowest IP address on the subnet is elected the IGMP querier. 3. All devices (excluding the querier) start the query timer, which is reset whenever a general query message is received from the IGMP querier. If the query timer expires, it is assumed that the IGMP querier has gone down, and the election process is performed again to elect a new IGMP querier.

in this document it mentioned highets IP addres. is teh answer highest IP? https://www.ciscopress.com/articles/article.asp?p=2738463&seqNum=6#:~:text=If%20there%20are%20multiple%20queriers,with%20the%20highest%20IP%20address.

lowest IP

when there are two routers in the same subnet then only one of them should send query messages. The election ensures only one router becomes the active querier. The router with the lowest IP address becomes the active querier.

sorry you're right uzbin , I read wrong, the one with the lowest IP
