On the Border Gateway Protocol > Global page, you can enable and disable BGP for Sophos UTM.
- To be able to enable BGP, create at least one neighbor on the Neighbor page.
On the Global page, enable BGP.
Click the toggle switch.
The toggle switch turns amber and the BGP System section becomes editable.
Make the following settings:
AS number: Enter the Autonomous System Number (ASN) of your system.
Router ID: Enter an IPv4 address as router ID which is sent to neighbors during session initialization.
Networks: Add or select the networks and/or hosts that should be announced to the neighbors by the system. How to add a definition is explained on the Definitions & Users > Network Definitions > Network Definitions page.
The toggle switch turns green and BGP becomes active. After a short time, the BGP Summary section displays status information.
Note – The network which is to be announced has to be assigned to a physical or virtual interface. Any request accessing a non-existing IP will loop between BGP neighbor and Sophos UTM.
