This Integer32 (1 to 255) sets the default Time-To-Live value inserted into the IP header of datagrams originated by this Virtual Router whenever the transport layer doesn't supply its own TTL. An admin tunes this to control how many hops packets originated by this virtual router can traverse before being discarded, which matters for controlling the reach of locally generated traffic like management pings or routing protocol packets. For example, an admin wanting to prevent a virtual router's originated traffic from accidentally routing beyond a small local network segment might lower csOrionVPNVRouterIpDefaultTTL well below the default 64 or 255 typically used.
