Explanation
In an IGMPv3-enabled VLAN, the IGMP querier is elected based on the lowest IP address among the participating routers. In this topology: Agg-1 has 10.1.0.2/24 Agg-2 has 10.1.0.3/24 The Active Gateway IP (10.1.0.1) is only for end-host default gateway redundancy, not used in IGMP querier election. Since 10.1.0.2 < 10.1.0.3, Agg-1 becomes the IGMP querier.
