Hello everyone,

Today I will share with you how to allow pass multiple VLAN from CE switch to server in VxLAN.


Problem Description

Detail information :

Device: CE6855

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

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

We already demo to our customer with this topology. But customer info to us, that their server existing uses some VLAN like the above topology (please refer to blue highlight).

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

094718g5uyen7ygssncnye.png

094721pc43yy7i9707k72z.png

094724zqdsqrqqagd1evj3.png

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

Problem Analysis

The configuration sample below that creates the sub-interface and gives 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 creates the sub-interface and gives 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

That is all I want to share with you! Thank you!

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.
