Re: [magma] Querier transition based on Group Specific Query?

[Bharat Joshi <[e-mail]>]

Hi Indranil,

      Is this defined in an RFC like that? Can you point me to the reference where it says what you mean below?

      I just did a google search on this and few top results for this seems to refer to general query only.

Regards,
Bharat

Hi Bharat,

              "IGMP Membership Query"query does not mean only General Query. It means both GQ and GSQ. Anything on this?

Thanks,
Indranil

Hi Indranil,

        I think a router should always be looking at general queries.

        This is what is available in RFC 2236:

>>>

  The following three events can cause the router to change states:

  - "query timer expired" occurs when the timer set for query
    transmission expires.

  - "query received from a router with a lower IP address" occurs when
    an IGMP Membership Query is received from a router on the same
    network with a lower IP address.

  - "other querier present timer expired" occurs when the timer set to
    note the presence of another querier with a lower IP address on the
    network expires.

<<<

    The second point clearly says that it should be an "IGMP Membership Query" which can trigger a change in querier state.

Bharat

Subject: [magma] Querier transition based on Group Specific Query?

Hi,

  In the querier transition state machine, RFC 2236 only mentions 'Query' and does not specify GQ or GSQ. Can a querier transition take place based on GSQ? Or is it okay to for a querier to ignore GSQ? Can anyone please help me with this?

Thanks,
Indranil
