one-interface routers and links (again)
Let me first describe one-interface routers as I understand are
proposed in 6LoWPAN:
+------------------------+---------------+
| | |
2001:db8:1::1/128 2001:db8:1::2/128 2001:db8:1::3/128
_|eth0 _|eth0 _|eth0
|R1 | |R2 | |R3 |
--- --- ---
R1 sends an IP packet to R3 but this reaches only R2. R2 picks the
packet, looks at the dst address, finds it's not for self, consults
routing table, finds a host-based route and sends it to R3. This can
work ok.
Exactly, you pictured this nicely. This is how LoWPAN Routing works.
I'll get back to the definition of that in your other thread.
Ok...
If we say the dashed line is The Link then we're in the ND case, any
node can talk to any other node at link-layer, no IP routing throughout.
But if it is not The Link, and it is not two times The Link - then what
is it?
What is the link definition needing a LoWPAN single-interface IP router?
