【Problem Description】

 


Detail information :

Device                    : CE6855

Problem                  : In VXLAN, how to allow pass multiple VLANfrom CE Switch to Server



All network running OSPF. This topology is VXLAN over IPsec.

We  already demo to our customer with thistopology. But customer info to  us, that their server exisiting usses some VLAN like above topology (please refer to bluehighlight).


For the port (10GE1/0/3.1 mode l2) CE Switch toward to server, I already configured like this :

094721pc43yy7i9707k72z.png

094724zqdsqrqqagd1evj3.png



Could the port allow pass multiple VLANs?If could, please give me advice for achieve that.



【Problem Analysis】


The configuration sample below that create the sub-interface andgive the dot1q vid for each vlan.

 

For example:

 

interface 10GE1/0/3.10 mode l2

encapsulation dot1q vid 10

bridge-domain 10

 

interface 10GE1/0/3.20 mode l2

encapsulation dot1q vid 20

bridge-domain 10

 

interface 10GE1/0/3.30 mode l2

encapsulation dot1q vid 30

bridge-domain 10


【Root Cause】
Configuration requite


【Solution Description】

The configuration sample below that create the sub-interface andgive the dot1q vid for each vlan.

 

For example:

 

interface 10GE1/0/3.10 mode l2

encapsulation dot1q vid 10

bridge-domain 10

 

interface 10GE1/0/3.20 mode l2

encapsulation dot1q vid 20

bridge-domain 10

 

interface 10GE1/0/3.30 mode l2

encapsulation dot1q vid 30

bridge-domain 10

Virtual Extensible LAN (VXLAN) is a network virtualization technology that attempts to address the scalability problems associated with large cloud computing deployments. It uses a VLAN-like encapsulation technique to encapsulate OSI layer 2 Ethernet frames within layer 4 UDP datagrams, using 4789 as the default IANA-assigned destination UDP port number.[1] VXLAN endpoints, which terminate VXLAN tunnels and may be either virtual or physical switch ports, are known as VXLAN tunnel endpoints (VTEPs)

As server virtualization is being rapidly deployed on data centers based on physical network infrastructure, VXLAN offers the following benefits:

Supports a maximum of 16M VXLAN segments using 24-bit VNIs, allowing data centers to accommodate a large number of tenants.
Removes the need for non-VXLAN network edge devices to identify the VM MAC addresses, reducing the number of MAC addresses that have to be learned and enhancing network performance.
Decouples physical and virtual networks by using MAC-in-UDP encapsulation to extend Layer 2 networks. Tenants can plan their own virtual networks, not limited by the physical network IP addresses or broadcast domains. This greatly simplifies network management.
