Nexus 7K multicast problem between VRF in VCC

Hi,

We are trying to test multicast between VRFs configured on Nexus 7Ks. Two Nexus 7Ks are configured for VPC. Multicast Server is in one VRF where as Receiver is in another VRF. The two VRFs are connected to each other via Checkpoint Firewall (Active/Active cluster in unicast mode). All routes have been established and connectivity tested between multicast server and receiver using ICMP.

Using, windows mcast.exe multicast stream is generated from server (in one VRF) intended to be received by receiver (in second VRF). Every time, only one multicast packet is received by the receiver and rest all packets are being dropped.

Server and Receiver are VirtualMachines configured on VMWaresame chassis which is connected to two Nexus 5Ks (VPC configured).

Hello,

Based on the description of your issue this may require live troubleshooting so I would suggest you open a service request with TAC (link on the right).

Cheers,
