Feb 18, 2025 · vPC is a virtualization technology that presents both Cisco Nexus 9000 Series paired devices as a unique Layer 2 logical node to access layer devices or endpoints. vPC belongs to Multichassis EtherChannel (MCEC) family of technology.

Nov 15, 2022 · VXLAN is a technology that allows overlaying a Layer 2 (L2) network over a Layer 3 (L3) underlay with use of any IP routing protocol. It uses MAC-in-UDP Encapsulation. VXLAN solves three main problems: 16M VNIs (broadcast domains) versus the 4K offered by traditional VLANs. Allows L2 to be extended anywhere in an IP network. Optimized flooding.

Nov 27, 2024 · All VLANs that require communication traversing the vPC Fabric Peering must have a VXLAN enabled (vn-segment); this includes the native VLAN. Note For MSTP, VLAN 1 must be extended across vPC Fabric Peering if the peer-link and vPC legs have the default native VLAN configuration.

Jun 18, 2020 · 传统网络隔离技术是通过VLAN，通过手动配置交换机和 服务器 对vlan设置Tag域来实现网络隔离。 但是vlan Tag只有12 bits，只能表示4096个VLAN，无法满足现在海量的云计算租户。 虚拟机迁移过程中要保证业务不中断，特别是现在分布式系统中更是如此，要保证虚拟机的IP地址不变。 VXLAN很好的完成了上面的挑战，我们一起来看看VXLAN是什么？

Port-Channel for Peer Link definition (must have no physical members!) During this period, no traffic (vPC and Orphan) is attracted by this peer. Type-5 routes which are advertised using PIP. It allows PIP loopback to brought up before the VIP (Anycast) loopback.

Apr 29, 2024 · To support vPC in VXLAN/EVPN network, there are two things we need to solve: Having two VTEPs appear as one from VXLAN and EVPN perspective. Connecting leafs to run the function of vPC peer link and vPC peer keepalive link.

May 1, 2024 · Cisco vPC in VXLAN/EVPN Network – Part 2 – Configuring vPC When building leaf and spine networks, leafs connect to spines, but leafs don’t connect to leafs, and spines don’t connect to spines.

Apr 26, 2022 · The lacp vpc-convergence command can be configured in VXLAN and non-VXLAN environments that have vPC port channels to hosts that support LACP. PIM BiDir for VXLAN underlay with and without vPC is supported.

VXLAN is a solution to support a flexible, large-scale multitenant environment over a shared common physical infrastructure. The transport protocol over the physical data center network is IP plus UDP. VXLAN defines a MAC-in-UDP encapsulation scheme where the original Layer 2 frame has a VXLAN header added and is then placed in a UDP-IP packet.
