Customers who have not yet made their choice or in need of a full-scale infrastructure policy applications, Cisco offers the Nexus 9000 new features management level.
Level Control Cisco BGP Control Plane for VXLAN must provide operators with a multi-tenant cloud wishing to use the familiar functions of routing protocol BGP, ability to scale their network and give them greater flexibility in order to meet the demand for cloud-based network. Technology VXLAN, increasing the number of segments VLAN 16 million end nodes, does not determine the level of control and organize the discovery of hosts and end nodes by multicast, which limits scalability.
BGP Control Plane for VXLAN can become an alternative for the Nexus 9000 level-based management applications (Cisco Application Centric Infrastructure, ACI). ACI structure is based on routing policies VXLAN and controller applications, called the APIC (Application Policy Infrastructure Controller). “Here we are definitely dealing with alternative deployment model – said Michael Cohen, director of product management divisions Cisco Insieme Networks Business Unit. – It is less heavy, and some customers are already going to use it in their work ».
BGP Control Plane for VXLAN runs on stand-alone versions of the Nexus 9000, which for the translation mode ACI requires a software update.
From a direct answer to the question whether Cisco, along with existing controllers and ACI APIC APIC Enterprise Module, offer a separate controller for media BGP Control Plane for VXLAN, Cohen chose to avoid. Level control BGP Control Plane for VXLAN is for customers who do not wish to organize multicast routing scalability issues and fear associated with the blanket mailing. It eliminates the need for multicast and explore the creation of overlay tunnels VXLAN and network virtualization.
The new level of control is used to disseminate information about the expansion of the reach of overlay network address family Multiprotocol BGP VPN Ethernet (EVPN). EVPN forms the second level of technology VPN, BGP uses to control the sending and learning MAC-address detection end nodes VPN.
The address family EVPN carries information about the
The components of security and authentication BGP multiple rent increase safety and BGP policies help to increase scalability by limiting the routing updates where it is not required.
The level of control BGP Control Plane for VXLAN allows the Cisco Nexus 9300 and 9500 support VXLAN in multicast mode, and learning and using the control level BGP-EVPN. Support of two modes increases the stability of communication with the servers and edge switches through the effective use of the available bandwidth.
The Cisco Nexus 9300 can route traffic VXLAN overlay controller configured through Cisco APIC. In Cisco consider it significant advantage over competitors platforms constructed on the basis of decisions Broadcom Trident II (in particular, the front of the platform Arista). Routing VXLAN in peripheral networks allows customers to lower the border between overlays the second and third level to the level of access to the peripheral nodes, which simplifies scaling and elimination of network errors, provides transparent mobility, improves abstract connectivity and improves the quality of policies.
Level control BGP Control Plane for VXLAN is compatible with platforms that meet the preliminary specifications EVPN, certain IETF. Some vendors, including Juniper and Alcatel-Lucent, have already implemented or plan to implement support EVPN in their proposals network virtualization, and AT & amp; T and Verizon have been actively involved in the development of specifications IETF.
The level of control BGP Control Plane for VXLAN is already supported by the Nexus 9300 and 9500.
