version
Syntax version version
no version
Context config>service>vprn>igmp>interface
Description This command specifies the IGMP version. If routers run different versions of IGMP, they will
negotiate the lowest common version of IGMP that is supported by hosts on their subnet and operate
in that version. For IGMP to function correctly, all routers on a LAN should be configured to run the
same version of IGMP on that LAN.
For IGMPv3, note that a multicast router that is also a group member performs both parts of IGMPv3,
receiving and responding to its own IGMP message transmissions as well as those of its neighbors.
Default 3
Parameters version — Specifies the IGMP version number.
