(config) #. Re: Multicast in Nexus vPC environment problem What I meant to say, was the layer 3 interfaces will not participate in vpc and are regular L3 “no switchport” ports. Troubleshoot Scenario 1: Multicast traffic forwarding when FP enabled on vPC peer-link. With the below sample configuration, VNI 30000 is tied to the underlay multicast group or Destination Group 239.1.1.1. Also, and don’t forget about that, you have to modify the TTL of the multicast packets generated by VLC, if not, the first PIM router will drop the traffic. However, in IaaS like AWS this is not obvious as we are abstracted from the HW infrastructure. Multicast traffic is forwarded to only one receiver in vlan10 connected to primary vpc peer while the receiver connected to the secondary peer does not receive it. A: You can route multicast traffic within and between VPC attachments to a Transit Gateway. It does this in a highly available way, using many active links. Julio Cesar says: 17 Oct, '14 at 17:02. Reply. The active HSRP … VPC networks can be securely connected in hybrid environments by using Cloud VPN or Cloud Interconnect. The canonical example is live video. Querier is needed when you enable traffic flowing within the same vlan so the traffic does not need to be routed. You can use AMIs in Amazon VPC that are registered within the same region as your VPC. interface nve 1 member vni 30000 mcast-group 239.1.1.1. vPC+ is an extension to traditional vPC. Enhanced vPC is a method that allows the connection of FEX in an active-active manner using vPC between the FEX and upstream Nexus switch, and at the same time connection of a device to the FEX host interfaces with a vPC. But multicast wasn’t designed for wireless, and especially isn’t well suited for high-bandwidth multicast applications like video. ... see the Cisco Nexus 7000 Series NX-OS Multicast Routing Command Reference.

Multicast still uses g speeds so the available physical rates are 6, 9, 12, 18, 24, 36, 48 and 54Mbps. VLAN 10 uses 192.168.10.0/24 and VLAN 20 uses 192.168.20.0/24. These are trunked via a VPC to the local 9k leafs to interconnect with the fabric. The IGMP process supports all VRFs in that VDC and performs the function of IGMP snooping within that VDC. When fabricpath running only between vPC link, the multicast traffic from host traverses over Peer-link to upstream router Multicast Open Shortest Path First (MOSPF) is an extension of the OSPF routing protocol, which enables multicast routing within an OSPF-based network. If there are layer 3 receivers on a layer 3 port or a non-vPC VLAN, bind-vrf must be configured per VRF in order for those receivers to receive the Multicast … Network Diagram. Multicast routing is not supported over AWS Direct Connect, AWS Site-to-Site VPN, and peering attachments. These VPNs allow service providers to provide private IP service to customers over a single Layer 3 network. You can configure PIM for an IPv4 network and PIM6 for an IPv6 network . It connects Classical Ethernet devices to a Fabricpath domain. The problem comes when you need to transmit around 400 Mbps to more than one EC2 instances that may be hosted in any physical server. Traffic within a VPC network doesn't count against bandwidth usage. Multicast sent to fex on vlan 50 (vpc vlan), in this case , both Switch A and Switch B have OIF for VRF B as the source is directly connected to it and it is in vpc vlan.

SVI's are running IP PIM-SM) 4 x Nexus 7710 (2 in each DC) Each Nexus is running VPC to each other and other, also other switches on the network connect to Nexus A and B by Port-channel VPC.

They do not support broadcast, multicast, or IPv6 traffic within the network; VMs in the In addition the vPC peer-link provides the necessary transport for multicast, broadcast, unknown unicast traffic and for the traffic of orphaned ports. Multicast Traffic is not equally distributed between Port-Channels as well as links within Port-Channel. Hi, I have 2 data centres connected across a Spine/Leaf fabric using BGP EVPN. I have 2 Data Centres setup with Virtual Buildings (i.e - 1 host in each building on the same subnet. Transit Gateway supports routing multicast traffic between subnets of attached VPCs and serves as a multicast router for instances sending traffic destined for multiple receiving instances. I don’t know if this would help, but if you are operating your workloads within an AWS VPC, you can create an overlay multicast within the VPC environment. IGMP snooping software examines Layer 2 IP multicast traffic within a VLAN to discover the ports where interested receivers reside. Not too sure on the multicast front as we don't use it in our environment and I haven't really looked into its behaviour on the 7K's. For information about IGMP ... the vPC peer link also carries multicast and broadcast data traffic. Usually if you are running a routing protocol down on the switch stack the recommended design would be to not have it as a member of a vPC and just use OSPF to give you the same advantages that vPC gives you at L2.
