Hi all,
   Just reading the above RFC and have come across the
following snag.

Looking at the packet format it states that "The
portion of the datagram from 'address family
identifier' through 'metric' may appear upto 25 times"

On the next page it also states that "The maximum
datagram size is 512 octets. This includes only the
portions of the datagram described above. It does not
count the IP or UDP headers."

Now, from the 'address family identifier' to the
'metric' field inclusive of each is 20 octets, which
when we have 25 entries yields 25 x 20 or 500 octets.
Add on the 4 octets from the 'command' field to the
'must be zero' field and we have 504 octets only.

Obviously if we add the UDP header we can get 512
octets. So something appears to be amiss or am I
missing something ?

Phil.
