L2TP、VxLAN、IKEv2 IP Security都是采用UDP封装。3.3 IP Protocol 数量有限 一个字节，理论上可以提供...
Layer 3 interconnection of the campus network is the basis of the virtual network. If Layer 3 interconnection has been implemented on the live campus network, step 1 in this example can be omitted. Procedure Configure a routing protocol. ...

The VXLAN buzz started during a keynote at VMworld in August 2011, when VMware CTO Steve Herrod announced the Virtual eXtensible LAN protocol, which VMware positions as a technology that “enables multi-tenant networks at scale, as the first step towards logical, software-based networks that can...
In addition to the technical details, this document presents design considerations and sample configurations to illustrate the EVPN Multi-Site approach. The VXLAN Border Gateway Protocol (BGP) EVPN fabric (or site) can be extended at Layer 2 and Layer 3 with various technologies. Howe...

When an application component initiates communication with another component, it operates just as it would in a non-VXLAN environment. If the destination is on the same subnet, it uses an Address Resolution Protocol (ARP) broadcast message to locate the other component. If the destination is on...
Configure the peerlink (peerlink.4094) between the MLAG pair for VLAN protocol 802.1ad. You cannot use the peerlink as a backup datapath in case one of the MLAG peers loses all uplinks. For switches with any type of Spectrum ASIC, when the bridge VLAN protocol ...
