(config) #. The canonical example is live video. More information is available in the Amazon EC2 Region and Availability Zone FAQ . In an on-premise datacenter with switch having IGMP snooping, the advantage of multicast is obvious. Querier is needed when you enable traffic flowing within the same vlan so the traffic does not need to be routed. vPC+ is an extension to traditional vPC. Self-Management of Multicast group membership by hosts through the Internet Group Management Protocol (IGMP) is not yet supported. They do not support broadcast, multicast, or IPv6 traffic within the network; VMs in the Traffic within a VPC network doesn't count against bandwidth usage. I have 2 Data Centres setup with Virtual Buildings (i.e - 1 host in each building on the same subnet. Hi, I'm currently studying multicast and I'm having a hard time thinking on how it would work on a HSRP environment. Troubleshoot Scenario 1: Multicast traffic forwarding when FP enabled on vPC peer-link.

Multicast routing is not supported over AWS Direct Connect, AWS Site-to-Site VPN, and peering attachments. In addition the vPC peer-link provides the necessary transport for multicast, broadcast, unknown unicast traffic and for the traffic of orphaned ports.

Multicast Open Shortest Path First (MOSPF) is an extension of the OSPF routing protocol, which enables multicast routing within an OSPF-based network. It connects Classical Ethernet devices to a Fabricpath domain. 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. Overview; Quickstart; How-To 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. In this paper, the focus is on the In this paper, the focus is on the differences between the IOS and the Nexus OS. Let's say for example I have 2 VLANs, VLANs 10 and 20. Live audio and stock market data are also common examples. IGMP snooping limits to distribution of multicast within a subnet, but is not relevant to routing multicast between subnets. Network manager Being able to set this is probably the most important criterion for a multicast AP. ... see the Cisco Nexus 7000 Series NX-OS Multicast Routing Command Reference. But first, an overview of multicast: To level set, I'll briefly cover IP multicast. Multicast across Data Centres OTV & VPC.

The Layer-2 virtual network has presence on V2 and V3, and the above configuration is applied similarly on V2 and V3 too.

Multicast is a communication protocol used for delivering a single stream of data to multiple receiving computers simultaneously. Associate VPC attachments and subnets with a transit gateway multicast domain Use the following procedure to associate a VPC attachment with a multicast domain. In a virtual Port Channel (vPC) topology, multicast traffic from a vPC port arrives on either of the vPC peers due to port-channel hashing. In some link failure scenarios, it also carries unicast traffic. 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. Consider for a moment that you have an application running on a server that needs to push some data out to multiple consumers and that every consumer needs the same copy of the data at the same time. There may be some hair-pinning happening within the interconnect architecture on the N7K if you are using F series cards that is being detrimental to routed traffic. For information about IGMP ... the vPC peer link also carries multicast and broadcast data traffic. VPC networks only support IPv4 unicast traffic. Multicast has brought a lot of efficiencies to IP networks. A: You can route multicast traffic within and between VPC attachments to a Transit Gateway.
Multicast still uses g speeds so the available physical rates are 6, 9, 12, 18, 24, 36, 48 and 54Mbps. 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. 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. You can configure PIM for an IPv4 network and PIM6 for an IPv6 network .

This usually happens at the Operating System level . In one DC I have UCS and in the other legacy Dell servers running ESX conected to catalyst switches. These VPNs allow service providers to provide private IP service to customers over a single Layer 3 network. However, in IaaS like AWS this is not obvious as we are abstracted from the HW infrastructure. I'll cover the challenges of multicast over wireless and design considerations. The active HSRP … In Cisco NX-OS, multicast is enabled only after you enable the PIM and PIM6 feature on each router and then enable PIM or PIM6 sparse mode on each interface that you want to participate in multicast. vPC connects hosts and other devices to the network.
