A few more comments: Section 3: What are the procedures if "reply via control plane" is requested for an LSP set up with LDP? (presumably some error results) Any plans for IPv6 reply modes? How about "return subcode MUST be set to zero."? Section 3.2: I'm unable to understand this explanation. Should the statement be "...compute which LSRs could receive the packet with TTL=n-1...." as in "what is the set of reasonable next hops?". Or is it "which LSR will receive this packet with TTL=n-1..." as in "if there are multiple NHLFEs, which one would this specific probe resolve to?". I believe I asked this last time around (00 version) and did not get an answer. A re-write of this paragraph would be useful. Section 4.2 If the probe is not well formed... presumably the reply mode for the error is as requested (incl. no reply)? Section 4.2: "if the echo request is good...is valid for the FEC....if not L MAY log this fact. " Seems to me that this fact is relatively useless unless all the circumstances associated with the test (in particular what 127. address was used by the echo request and who the probe originated with) are logged. Otherwise a craftsperson may be obliged to do extensive testing to reproduce the circumstances of the test. And if one is using "no reply" mode, the stipluation should be stronger than a "MAY". thx Dave |
