IGMP Snooping configuration for Multicasting on Cisco Catalyst 3020

cisco_dba · ‎11-25-2011

Hi Guru,

Our switch model is "Cisco Catalyst Blade Switch 3020 for HP"

We are building HA (High Availability) Databases infrastructure.

Currently, there are two nodes(hosts- servers) and two above switch for HA.

Oracle said we need to turn off the IGMP Snooping in order to use the multicasting for their interconnect communication.

So my question is:

Q1> Is there any way to use Multicasting without turning off IGMP Snooping on Switch side?

Q2> If 'yes', how can we configure the switch for Multicasting ?

Oracle uses 230.0.1.0 & 224.0.0.251 IPs with 42000 range port for Multicasting communication.

Please shed some light on it

May I request if you avoid making multiple posts of the same issue? This will only confuse people (including you).
