COMMENT:
----------------------------------------------------------------------


- 5.1: Is a modem supposed to ignore peer discovery
signals from routers with which the modem does not have a
TCP connection?

- 10.7: This says: "If the modem is capable of
understanding and forwarding this information (via
mechanisms not defined by DLEP)," I don't get why that's
here, can you explain? If modem-modem comms is part of
DLEP deployments (even if not fully spec'd) then that does
change the security model.

- 10.9 and elsewhere: none of these messages have anything
like a cookie. Why not? That'd help mitigate potential off
path attacks, where we currently depend solely on TTL=255
(and TLS, which seems to not be some people's favourite;-)

- 11.8/9: are there any special addresses that MUST NOT
occur here? E.g. ::1, 127.0.0.10? What about the addresses
IANA allocates for you from 13.14/15?

- 11.10/11: what does prefix=0 mean?

- I agree with Alexey's DISCUSS#3, the TLS stuff needs
more work to be usable. Maybe recommend PSK?
