1. Configure the AW peer to send out a community number 89:89

add ip routem=com entry=1 set commmun=89:89

set bgp peer=45.45.45.45 outroutemap=com sendcommunity=yes

The routes coming from that peer has community 89:89

1.Then, on the AlliedWare Plus switch, create a community-list that matches on some community values.

ip community-list 78 permit 55:66 ip community-list 78 permit 89:89 ip community-list 78 permit 9999:89

2.Create a prefix-list that matches the route 52.0.0.0/8 ip prefix-list test1 permit 52.0.0.0/8

3.Set the community-list to be the match criterion on a deny entry in a route map route-map com deny 1

match community 78

This makes it suitable for data centers and large enterprise networks where space and bandwidth optimization are critical.

In addition to scalability, the x908 series supports advanced Layer 2 and Layer 3 switching capabilities. This allows for efficient traffic management and routing, ensuring that data is delivered swiftly and reliably. The x908 also incorporates intelligent features such as Quality of Service (QoS), which prioritizes critical network traffic, ensuring that time-sensitive data—like voice and video—maintains its quality during transmission.

The SwitchBlade x900 series takes this functionality further with its innovative modular architecture. This allows organizations to configure their networks to meet specific needs by choosing from a variety of interface cards and service modules. The SwitchBlade x900 also supports advanced security features such as Access Control Lists (ACLs) and VLAN segmentation, which provide enhanced protection against unauthorized access and network threats.

Another hallmark of the x908 and SwitchBlade series is their support for high-speed Ethernet technologies, including 10G and 40G Ethernet. This enables organizations to keep pace with the increasing bandwidth demands of applications and services, particularly in cloud computing and data-intensive workloads.

Both the x908 and the SwitchBlade x900 series are designed with energy efficiency in mind, featuring power-saving technologies that reduce overall operational costs. Coupled with Allied Telesis' management tools, which provide detailed analytics and monitoring, network administrators can optimize performance and energy consumption simultaneously.

In summary, the Allied Telesis x908 and SwitchBlade x900 series offer a comprehensive suite of features, high performance, scalability, and advanced networking technologies.
