The fields that can be configured in BGP Parameters are described below: Parameter BGP Router Identifier Synchronization Enforce First AS Scan Time Keep-Alive Interval Description Enter the router ID in the IPv4 address format as the identifier of the local BGP router here. Select to enable or disable synchronization here. When synchronization is enabled, the BGP speaker will not advertise a route to an external neighbor unless the route is a local route or the BGP speaker has learned the route by IGP. Select to enable or disable the enforced first AS feature here. This is used to enforce that the routes received from an eBGP peer must have the peer's AS number as the first AS in the AS path. This feature is used to avoid the local router from spoofing by a misconfigured peer. Enter the scan time value here. When the router is enabled for scanning next hop of BGP routes, the router will periodically check whether there is a route to reach the next hop in the routing table. The range is from 5 to 60 seconds. Enter the keep-alive interval value here. This specifies the interval that the software uses to send keep-alive messages to BGP peers. The range is from 0 to 333
