On a VLAN I enable IGMP version 3:
ip igmp version 3
with "show ip igmp interface" I see:
Internet address is 10.88.10.254/24
IGMP is enabled on interface
Current IGMP host version is 2
Current IGMP router version is 3
1) What does "Current IGMP host version is 2" mean ? Is t configurable the same as the router version ?
2) Can I have hosts that uses IGMPv2 and IGMPv3 on the same LAN ?
1) AFAIK, No.This means the hosts can be either v2 or v3.
2) Yes.Both v2 and v3 hosts can coexist.But you should implement one of the transition solutions like URD, v3lite or SSM mapping so that v2 reports are interpreted correctly.
