The Border Gateway Protocol (BGP) is a routing protocol that consists of a set of rules that determine the best network routes for data transmission on the internet.
Within a NetCloud Exchange Secure Connect network, BGP can be used in the following scenarios:
Large deployments where the core network and the site routers need to communicate at scale.
Cold Standby setups, to enable automatic updates of the lan0 routes from the primary to the secondary NetCloud Exchange Service Gatewayand vice versa during failover and failback.
Data center deployments where BGP is leveraged.
BGP can only be configured on an existing NetCloud Exchange Secure Connect network.
Note
NetCloud Exchange BGP does not track tunnel status. The NCX Service Gateway does not stop advertising prefixes for a site’s IP subnet resources, even if the tunnel to the Secure Connect site router is down.
