i have two severs IBM are working as a cluster and connected to Fiber fabric extender 2K using VPC as per attached diagram
two IBM server are woriking fine for network connectivity with N2k but the servers have a multicast named ( power HA 7.1) to work as acluster
but i tried to configue multicat in N7K and N2k to server working as acluster but the servers are not working
please advice me about the configuration in N7K and N2k to working IBM servers as a cluster .
Use a link local address 220.127.116.11/24 if configurable; if not :
- igmp snooping querier
- if your multicast cluster doesn't use IGMP; disable IGMP snooping on the vlan
the IBM server have ip multicast 18.104.22.168
i configured the command above but not working
One option is the IGMP querier:
config t ip igmp snooping vlan 2
switch(config-vlan-config)# ip igmp snooping querier 10.0.10.253
(or a good source address of the interface)
The other option is run PIM on the VLAN interface:
ip pim sparse-mode
Both has the same purpose: combined with IGMP snooping, the L3 interface will flood the VLAN with IGMP queries that traverse the inter-switch links. As a result, the inter-switch links will be included in the snooping port list. In turn,
packets destined to 22.214.171.124 will be sent out the inter-switch link and reach the other server.
Without the IGMP queries, 126.96.36.199 packets will not be sent from one switch to the other as it is not in the 188.8.131.52/24 range.
