The value of tBgpInstanceAddPathEnable specifies whether the BGP ADD-PATH send capability is enabled on this BGP instance. ADD-PATH allows a BGP router to advertise multiple distinct paths for the same prefix/NLRI(Network Layer Reachability Information). This capability provides a number of potential benefits like reduced routing churn, faster convergence, better loadsharing etc. When the value of tBgpInstanceAddPathEnable is set to 'true', the BGP ADD-PATH send limit objects tBgpInstanceAddPathIpv4Limit, tBgpInstanceAddPathVpnIpv4Limit, tBgpInstanceAddPathIpv6Limit, tBgpInstanceAddPathVpnIpv6Limit, tBgpInstanceAddPathLblIpv4Limit, and tBgpInstanceAddPathLblIpv6Limit represent their assigned values. The default value of tBgpInstanceAddPathEnable is 'false', which means the ADD-PATH capability is disabled on this BGP instance and the values of the BGP ADD-PATH send limit objects are not valid.
