I can see the argument for per-tunnel knobs, but looking at ios and nx-os docs it seems appropriate to have a global knob as well. In that regards having sysctl knobs solves the global setting and when/if needed we can add MPLS_IPTUNNEL_ZZZZZ encap attributes for the per-tunnel settings. Does that seem reasonable?
