In that situation, we are actually using it as a L3 core/distri/access, using VPC, HSRP, OSPF and BGP, with of course all basic Hi All, I'm currently working with a customer that have 4 x Nexus 9K switches, two in their primary data centre and two in their DR data centre. Cada par vPC de switches Nexus 9000 se conecta al par vPC de agregación con un vPC único. 1 source 169. This document describes the best practices to use for virtual Port Channels (vPC) on Cisco Nexus 9000 (9k) Series Switches. Seeing a couple conflicting options so hoping for guidance on the best option. Log into Software Download ; Navigate to section Download and Upgrade and open Access Downloads. D. I would like the HSRP traffic to communicate between the nexus in each DC but not inter-DC. VM resources: 4*CPUs( E7- 4870 @ 2. At the time of flood i see errors on VPC primary: # s 本文档介绍 Cisco Nexus 9000 (9k) 系列交换机上用于虚拟端口通道 (vPC) 的最佳实践在双面vPC中，两台Nexus 9000交换机都运行vPC。Nexus 9000 交换机的每个 vPC 对都连接到具有唯一 vPC 的汇聚 vPC 对。 Hello, Topology is as follows: vPC Domain 10 NX5k_A peer member is connected to NX5K_B peer member via peer-link port HostZ is connected to both vPC peers using a vPC114/port-channel114) HostZ is using vPC VLANs (VLANs are members of the peer-link) HostZ is an ESXi. 0 (3)I4 (1), you can enable PIM SSM on Cisco Nexus 9000 Series switches with an upstream Layer 3 cloud along with the vPC feature. When i reboot one of the nexus, traffic continues to flow fine but when the nexus comes up again and restores the VPC portchannels, traffic stops flowing. 10. Layer 3 over vPC is not supported for Layer 3 multicast To enable multicast and IGMP: --Enable multicast routing by configuring the PIM protocol. 27 MB) View with Adobe Reader on a variety of devices. See more This chapter describes how to configure the Protocol Independent Multicast (PIM) features on Cisco NX-OS devices in your IPv4 network. 0, 9484548. vPC in a Nutshell. I am facing an issue with multi casting in cisco switches . The AV sender/management device is on one of these access switches and the receivers are connected to different access switches, all devices are on a dedicated VLAN and everything seems to work fine for normal Configure the vPC peer gateway to enable the HSRP routers to directly handle packets sent to the local vPC peer MAC address and the remote vPC peer MAC address, as well as the HSRP virtual MAC address. Verwenden Sie in der vPC-VXLAN-Fabric eine separate Loopback-IP-Adresse für I have two Nexus 9k's in a VPC receiving multicast data. • Nexus 9500 modular switches with Cloud Scale linecards • Nexus 9300 Cloud Scale top-of-rack (TOR) switches • System and hardware architecture, key forwarding functions, packet walks Not covered: • First generation Nexus 9000 ASIC/platform architectures • Nexus 9500 merchant-silicon based architectures • Other Nexus platforms Cisco vPC was first introduced in Nexus 5000/7000 platforms and continues to be popular on Nexus 9000 platforms. system routing template-multicast-ext-heavy. Perform the initial configuration of each VTEP switch. In vPC system ,the primary switch will process and reply for BPDU and it is the primary switch which will send the STP Root Bridge information to all switches which are part of vPC system. The setup works fine, with two nexus in VPC on one side and another two nexus in VPC on the other side. This question is better fit on the Community Forum "Data Center Switches" since it pertains to standalone Nexus running in NX-OS and not in ACI mode. vpc is setup from 53<>53 and 54<>54 with mgmt as the heartbeat. Nexus status and config: sh vpc brief Legend: Please check "show vpc consistency-parameters vpc <vpc-num>" for the consistency reason of down vpc and for type-2 consistency reasons for any vpc.

Port-channel 10 is the vPC peer link and is up. storm-control multicast level 100. 2 source 192. The source and destination IP supported in virtual peer-link destination command are class A, B, and C. many topics on multicast today I'm feeling pretty lost with it and would appreciate some guidance as what I want to achieve I think is much simpler En vPC de doble cara, ambos switches Nexus 9000 ejecutan vPC. --Configure the necessary multicast groups and Step 2. IGMP is a new concept to me, but I think I understand the generics of it. However, Prod-Nexus-Pri should not be able to communicate via hsrp to DR-Nexus-Pri, It is recommended to use the vpc orphan-ports suspend command for single attached and/or routed devices on a Cisco Nexus 9000 platform switch acting as vPC VTEP.
