Cisco otv vdc Notice how OTV is deployed on the OTV VDCs connected to the aggregation layer leveraging port channels as internal interfaces (vPC based POD). In this figure, the Agg VDC contains all the configuration and physical links for the Aggregation Layer of a data center. Hardware Platform Supported. Nexus 7000 Cisco Data Center Interconnect Overlay Transport Virtualization 1 OTV Technology Introduction and Deployment Considerations This document introduces a Cisco innovative LAN extension technology called Overlay Transport Virtualization (OTV). Connectivity will be verified via ping between two N7K. This chapter describes how to configure basic Overlay Transport Virtualization (OTV) features on Cisco Nexus 7000 series NX-OS devices, including how to create an overlay interface, extend VLANs over the overlay network, and assign a multicast group to the overlay network. In order to simulate the production environment in test, one Nexus was dedicated to the Server Farm Access tier. OTV uses MAC address-based routing and IP-encapsulated forwarding across a transport network to provide support for applications that require Layer 2 adjacency, such as clusters and virtualization. " Mar 14, 2020 · OTV currently enforces switch-virtual-interface (SVI) separation for the VLANs being extended across the OTV link, meaning that OTV is usually in its own VDC. 7. 2/24 OTV VDC: N7K-Site-2-OTV# sh port-channel summary interface po43 Oct 8, 2024 · After you create the storage VDC, you assign specified FCoE VLANs. When using a separate VDC for OTV functions, two deployment models are possible (Figure 1): OTV Appliance on a Stick Inline OTV Appliance Oct 28, 2010 · OTV-VDC-A(config-if)# otv control-group 239. Sep 29, 2017 · Configure OTV including the VLANs that will be extended. Oct 28, 2010 · All the technology and deployment considerations contained in this paper focus on positioning the Nexus 7000 platforms inside the data center to establish Layer 2 connectivity between remote sites. As stated by the Guidelines and Limitations for OTV, "If the same device serves as the default gateway in a VLAN interface and the OTV edge device for the VLANs being extended, configure OTV on a device (VDC or switch) that is separate from the VLAN interfaces (SVIs). OTV is also not supported by 9k however, they can pass the OTV encapsulated traffic. After the OTV adjacency is setup, OTV process creates implicit tunnels for each discovered peer. X. ( (can you explain compare with FabricPath if you have example?) 6. Cisco Data Center Interconnect Overlay Transport Virtualization Appendix A Complete OTV Configuration NR-n7k-a version 5. Verify Tunnel Creation. Oct 27, 2010 · As mentioned in the configuration guide, the OTV edge device/VDC cannot also be a gateway for VLANs transported on the overlay, hence the common designation of a VDC for OTV purposes with a physical loopback to the VDC with SVIs. Moving all SVIs off the Nexus 7000s would be the only way OTV can function in your topology without the VDC license. 1(1a) license grace-period hostname NR-n7k-a!Following configuration set is not terminated by a newline no vdc combined-hostname vdc NR-n7k-a id 1 limit-resource vlan minimum 16 maximum 4094 Feb 21, 2013 · OTV has the following configuration guidelines and limitations: If the same device serves as the default gateway in a VLAN interface and the OTV edge device for the VLANs being extended, configure OTV on a device (VDC or switch) that is separate from the VLAN interfaces (SVIs). Hello @bienfaits As of my knowledge, multi VDCs are supported by 7K, and 77K series 9Ks support single VDC. OTV is an IP-based functionality that has been designed from the ground up to Jan 29, 2014 · This document covers basic OTV configuration and Verification between two N7K Each N7K configured with two VDC OTV VDC Core_VDC VLAN 2 configured on Core_VDC of both N7K, and extending VLAN 2 traffic between two N7K via OTV VDC. The following device configurations are relative to the setup in Figure A-1. X otv data-group X. Feb 21, 2013 · OTV is a MAC-in-IP method that extends Layer 2 connectivity across a transport network infrastructure.

Define the OTV data-group used to map the sites' multicast groups to a range of SSM addresses in the transport network to carry the sites' multicast traffic. Does OTV Require a Separate VDC? OTV currently enforces switch-virtual-interface (SVI) separation for the VLANs being extended across the OTV link, meaning that OTV is usually in its own VDC. BRKDCT-3470: Cisco Nexus 7000 Switch Architecture. 0/26 A common question is related to the dimensioning of the data-group. otv vdc As stated by the Guidelines and Limitations for OTV, "If the same device serves as the default gateway in a VLAN interface and the OTV edge device for the VLANs being extended, configure OTV on a device (VDC or switch) that is separate from the VLAN interfaces (SVIs). If not, the data will not be forwarded across the OTV even though the OTV overlay is up and adjacency is forwarded with other peers. Sep 8, 2014 · OTV in a VDC. OTV support on Nexus 7000 platforms has been introduced from the NX-OS 5. The other switch hosted a Core tier VDC and a Server Farm Distribution tier VDC. Cisco refer to this design as VDC Vertical Device Consolidation. 1 f. The test environment had only two Nexus switches. meaning that OTV is usually in its own VDC. The number of VDCs that can be created is dependent upon the version of NX-OS, the Supervisor model and the license installed. Topology Jan 8, 2015 · 5. OTV is the fault-domain isolation feature. 1. Finally, you configure interfaces on the Cisco Nexus 7000 Series device as either dedicated FCoE interfaces or as shared interfaces, which can carry both Ethernet and FCoE traffic. 10. Hence the load balancing the links is not efficient. VLAN scalability for OTV is lower than FabricPath as of this content writing. Typically two flows (Odd VLANs by OTV-VDC-1 and even vlans by OTV-VDC-2) carry the entire layer 2 traffic flow between the two Data Centes. FCoE commands Cisco NX-OS FCoE Command Reference for Oct 8, 2024 · The following Cisco Nexus 7000 Series Ethernet modules have the following number of port groups and interfaces: N7K-F132XP-15 (2 interfaces x 16 port groups = 32 interfaces)—There are no restrictions on the interface allocation between VDCs, but we recommend that interfaces that belong to the same port group be in a single VDC. 0 (3) software release. 1 otv data-group 232.

With the VDC license on the Cisco Nexus 7000 Series you have the flexibility to have SVIs in other VDCs and have a dedicated VDC for OTV functions. This figure shows one physical switch with a VDC for OTV configuration and a VDC for the Aggregation Layer (Agg VDC) configuration in a data center.
