Hi Yakov, > After all, these IGP-based tunnels are *not* source/explicitly routed.
The definition of "source routing" states that source routing is the ability which allows a sender of a packet to partially or completely specify the route the packet takes through the network Let's notice that it says nothing about the src of such information. Such source of this information can be coming from various sources or routing protocols including IGPs. Charter says: " Full explicit control (through loose or strict path specification) can be achieved in a network comprising only SPRING nodes, however SPRING must inter-operate through loose routing in existing networks and may find it advantageous to use loose routing for for other network applications." The above quite directly allows SPRING WG to work on "loose paths" and "loose routing" therefor IGPs can be used just fine to propagate such explicit control information. Thx, R.
