The BGP dynamic routing protocol

Kaspersky SD-WAN supports the use of the BGP (Border Gateway Protocol) dynamic routing protocol to exchange routing information between CPE devices connected to your SD-WAN network, as well as with third-party network devices. You can establish both internal iBGP (internal BGP) sessions and external eBGP (external BGP) sessions.

Dynamic TCP sessions with groups of BGP peers (BGP peer groups) are also supported. Establishing a dynamic TCP session avoids the need to create individual BGP peers.

The figures below show examples of BGP being used in the solution:

• Connecting multiple client locations to the L3 SD-WAN network via BGP.

  

• Connecting CPE devices to the service provider's IP/MPLS network via BGP.

  

• Using BGP to configure the connectivity of CPE devices within a Kaspersky SD-WAN domain.
