Example A A route map that matches on a prefix-list and sets the route metrics

1.Create a prefix list that matches just 52.0.0.0/8

awplus(config)#ip prefix-list test1 permit 52.0.0.0/8

2.Then, create a route map to match on this prefix-list, and set the metric of matching routes to 665:

awplus(config)#route-map test1 permit 1 awplus(config-route-map)#match ip address prefix-list test1

awplus(config-route-map)#set metric 665

3.Configure the route-map to operate on incoming updates from neighbor 45.45.45.46 awplus(config-router)#neighbor 45.45.45.46 route-map test1 in

Example B Match on a prefix-list that denies an entry

1.Create a prefix list that excludes 52.0.0.0/8, then includes all other routes: awplus(config)#ip prefix-list test2 deny 52.0.0.0/8 awplus(config)#ip prefix-list test2 permit any

2.Create a route map to match on this prefix-list:

awplus(config)#route-map test2 permit 1 awplus(config-route-map)#match ip address prefix-list test2 awplus(config-route-map)#set metric 665

The route map is:

route-map test2, permit, sequence 1 Match clauses:

ip address prefix-list test2 Set clauses:

metric 665

3.Shut down the neighbor, and then bring it up again:

awplus(config-router)#neighbor 45.45.45.46 shutdown awplus(config-router)#neighbor 45.45.45.46 no shutdown

4.Check the route table. This time, the only route learnt from the peer is 45.0.0.0/8, and it still has metric 665. The prefix-list has explicitly matched all routes except 52.0.0.0/8, so all routes except 52.0.0.0/8 have been permitted by the first entry of the route map. Then 52.0.0.0/8 has been denied by the implicit deny-all entry at the end of the route map.

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. They represent a strategic investment for organizations looking to build resilient, efficient, and future-proof network infrastructures.
