Overview
VXLAN source-based ingress replication is a feature of VXLAN that allows a single packet to be replicated to multiple destinations based on the source IP address of the packet. This feature is useful in scenarios where you want to implement load balancing or failover for applications that use VXLAN.
How it works
VXLAN source-based ingress replication works by using a hash table to map source IP addresses to a list of destination IP addresses. When a packet is received on a VXLAN interface, the source IP address of the packet is used to lookup the corresponding list of destination IP addresses. The packet is then replicated to each of the destination IP addresses.
Benefits
There are several benefits to using VXLAN source-based ingress replication:
* Load balancing: VXLAN source-based ingress replication can be used to load balance traffic across multiple servers. This can improve the performance of applications by distributing the load more evenly.
* Failover: VXLAN source-based ingress replication can be used to provide failover for applications. If one server fails, the traffic for that server can be automatically redirected to another server.
* Simplified configuration: VXLAN source-based ingress replication simplifies the configuration of load balancing and failover for VXLAN networks.
How to configure VXLAN source-based ingress replication
To configure VXLAN source-based ingress replication, you need to add the following configuration to your VXLAN configuration:
feature vxlan
interface
source-based-ingress-replication
Replace
Example
The following example shows how to configure VXLAN source-based ingress replication on the VXLAN interface vxlan1:
feature vxlan
interface vxlan1
source-based-ingress-replication
Conclusion
VXLAN source-based ingress replication is a powerful feature that can be used to improve the performance and reliability of VXLAN networks. It is easy to configure and can be used in a variety of scenarios.
