Hi all,
i'm implementig vxlan on the new version of 1000v (4.2.1.SV2.2.1a) on esxi5.5 and Vsphere 5.5. I try this in my lab.
I'm encountering some problems with the multicast implentation of vxlan, on a l2 mode between vsm and vem, and on a l2 domain.
I see the multicast correctly encapsulated by vtep vem, The bridge groups are ok , with the right Veths. But i 've some problems with the igmp ( no reports are receveid from esxi hosts)
The vtep interfaces receives the queries from the uplink switch :
cisco1000v_lab_l2(vem-attach)# vemcmd show vxlan interfaces
LTL VSM Port IP Seconds since Last Vem Port
IGMP Query Received
(* = IGMP Join Interface/Designated VTEP)
-----------------------------------------------------------
49 Veth1 172.28.19.98 27 vmk1 *
vem 4
cisco1000v_lab_l2(vem-attach)# vemcmd show vxlan interfaces
LTL VSM Port IP Seconds since Last Vem Port
IGMP Query Received
(* = IGMP Join Interface/Designated VTEP)
-----------------------------------------------------------
49 Veth2 172.28.19.99 10 vmk1
ONLY multicast is encapsulated, and no unicast and arp from the remote ip

I try to sniff the Multicast leaving/entering the VEM, and i see only the queries from my upstream switch to the 224.0.0.1 all host group.
But no one answer to the queries with a report message ...
With the vempkt command i capture in ingress only the query message entering the ltl 561 ( portchannel uplink for the vxlan in vlan 400)

NO report received from the veth1, corresponding to the vmk1 with vxlan capability...
Even with the capture egress, i see only the query from the upstream switch towards the veth1, vmk1, but not answer from the vmk1...
Can someone help me? Is there some incompatibility with the queries igmp send from the uplink switch 2960 c2960-lanlitek9-mz.122-58.SE2 and the esxi version 5.5 ? The configuration of 2960 is :
ip igmp snooping querier address 172.28.19.97
ip igmp snooping querier
I need to upgrade to new version of 1000v , but i must solve this problem first....
Thank in advance
Federica
