This object enables or disables next-hop-self behavior for eBGP sessions with all peers in this group, defaulting to notconfigured and disabled, overridable per neighbor. Administrators enable this at the group level when an entire set of peers, such as internal route-reflector clients, need the router to substitute itself as next hop. For example, an engineer enables csBgpNbrGroupNextHopSelf for a group of iBGP clients that have no direct routes to external eBGP next hops, letting them all route through this virtual router instead.
