I am trying to make the multicast working between few hosts inside a single vlan. Host are running mysql cluster and Multicast
is used to send master/slave status information to the IP 18.104.22.168 on port 45566.
The vlan is defined in FWSM and the host are connected via the core-switch(6513). (hosts-->core-sws--->fwsm)
I have tried searching the documentation, but couldn't find specific info to enable multicast between hosts residing in same vlan. FWSM is running code 3.1(4). since the hosts are residing in the same vlan, I am thinking of applying the <multicast-routing> just for that SVI in FWSM, Is this enough to make it working ?
Any advice is higly appreciated.
Thanks in Advance.
Many thanks for the Advice.
I have a question.
As per the Doc link, To enable the IGMP Snooping Querier, <ip igmp snooping querier> needs to
be applied on the inteface vlan and it needs to have a IP address. But in our scenario,
the SVI is created in the FWSM, not on the Core-Switch. So I am not able to apply the
command in core switch.
I have checked if the Querier option can be enabled globally, but seems like it is not possible,
CT-6513-CORE-I(config)#ip igmp snooping ?
l2-entry-limit limit on the l2 entry that can be installed by IGMP snooping
limit Configure IGMP Snooping limits
source-only-learning source-only gce entries
so the only option I have is to create another svi in core-switch and assign an IP address to make it working ?
Waiting for your reply.
Very good point and deserves a rating
Apologies for that as i didn't think it through very well. You are right in what you say.
So in actual fact your orginal idea of enabling multicast-routing is the way to go. This will enable pim and igmp on all the FWSM interfaces but you can disable it per interface with
fwsm(config-ip)# no igmp
fwsm(config-ip)# no pim
