How to set up BGP sessions on Ufispace devices

This article will show you how to create BGP sessions on Ufispace devices, as well as some examples of filters, prefix lists and community application. To work out the configurations, the following scenario will be used: BGP Policy: Default route announcement + local prefix; Accept only the 210.0.0.0/22 prefix with community tag 65000:1000; Both using a route map Default route prefix list configuration: Prefix-List configuration with prefixes 200.0.0.0/22 and 210.0.0.0/22, allowing up to /24: Route-Map configuration allowing ASN prefix 65010 and marking community 65000:1000 : Route-Map configuration to announce default route and 200.0.0.0/22 prefix: Configuration of blackhole routes (to avoid static loops and create routes in the routing table): Access BGP configuration by entering the Local AS: Configure Router-ID IPv4 network configuration: BGP neighbor configuration: Configuring BGP filters: Check configuration and apply: To check the status of the BGP session: Check what is being announced in the BGP session: Check what we have received as a prefix: Summary of all settings applied
