Re: 2401bis Issue # 84 -- DROP'd outbound packet
In your previous mail you wrote:
Type Name Reference
---- ------------------------- ---------
1 Destination Unreachable [RFC2463]
=> draft-ietf-ipngwg-icmp-v3-02.txt is more up to date.
0 - no route to destination
1 - communication with destination
2 - (not assigned)
=> reassigned to "beyond scope of source address"
3 - address unreachable
4 - port unreachable
b2. the IPsec system was unable to set up the SA required by the SPD
entry matching the packet because the IPsec peer at the other end of
the exchange could not be contacted. The type should be destination
unreachable, but what codes should we use?
IPv4 Type = 3 (destination unreachable)
Code = ??
IPv6 Type = 1 (destination unreachable)
Code = ??
=> IMHO the code should follow the reason why the IPsec peer could not
be contacted with code 1 by default?
