Sophos XGS bgp routing preference

Hi, 

The requirement can be achieved by configuring “weight” for the neighbors. The route from the neighbor configured with higher weight would be preferred and used as long as it is available. If that route goes down, the other route, with lesser weight, would be used.  

The option to set weight is to be done via the CLI configuration as below: 

bgp(config-router-af)# neighbor 1.1.1.1 weight 56 

The above configuration would set all the routing updates received from 1.1.1.1 to have a weight of 56. (without this config, by default, weight assigned would be 0) 

Hope this helps! 

Thanks, 

what is the command on the console. We currently receive the message "unknown command"

After navigating to the cli interface to configure BGP  [Option 3 (Route Configuration) > Option 1 (Configure Unicast Routing) > Option 3 (Configure BGP).], you need to give the cli in "address-family" prompt : 

bgp> en

bgp# conf t

bgp(config)# router bgp 300

bgp(config-router)# neighbor 1.1.1.1 remote-as 5

bgp(config-router)# address-family ipv4 unicast

bgp(config-router-af)# neighbor 1.1.1.1 weight 56

Pls save the config with the following cli: 

bgp(config-router-af)#write 

after the command "router bgp ***" we get the message " BGP is already running" can the weighting not be adjusted afterwards?

In the CLI "router bgp <n>" , the parameter "n"is the AS configured in the device.  Please use the exact ASN that has been configured in your device. 

We can configure/modify weight (or any other configuration) at any point of time. 

now we have changed the value. where can we see it now? with "show bgp ip" the value 0 is still displayed as "Weight"

You can check the configuration using the command "show running-config" in the enable prompt. Maybe re-establish the neighborships to make the new config effective?
