VXLAN Static Ingress Replication (SIR) is a feature that allows a VXLAN tunnel to be replicated to multiple destinations. This can be useful for load balancing or for providing redundancy.
Configuration
To configure VXLAN SIR, you will need to create a VXLAN tunnel and then configure the tunnel to use SIR.
To create a VXLAN tunnel, use the following command:
“`
vtep
“`
To configure the tunnel to use SIR, use the following command:
“`
vtep
“`
The sir-list is a comma-separated list of destination VTEPs.
Operation
When a packet is received on a VXLAN tunnel that is configured for SIR, the packet is replicated to all of the destination VTEPs. The destination VTEPs then decapsulate the packet and forward it to the appropriate destination.
Benefits
VXLAN SIR can provide the following benefits:
* Load balancing. VXLAN SIR can be used to load balance traffic across multiple destinations. This can help to improve performance and reduce latency.
* Redundancy. VXLAN SIR can be used to provide redundancy for VXLAN tunnels. If one of the destination VTEPs fails, the packet will still be replicated to the other destination VTEPs.
Considerations
There are a few considerations to keep in mind when using VXLAN SIR:
* Performance. Replicating packets to multiple destinations can impact performance. It is important to consider the performance implications of using VXLAN SIR before deploying it in a production environment.
* Security. Replicating packets to multiple destinations can increase the risk of security breaches. It is important to implement appropriate security measures to protect your network from unauthorized access.
Conclusion
VXLAN SIR is a powerful feature that can be used to improve the performance and reliability of VXLAN tunnels. By carefully considering the performance and security implications, you can use VXLAN SIR to create a robust and scalable network.
