knock knock! hello?
I know what ARP is used on LANs for, but as you can see, the misterious
"ARP packet" has many types, as many as 15 at least, since type 15 is a FR
specific one, and I quote from the /usr/include/linux/if_arp.h file again:
#define ARPHRD_DLCI 15 /* Frame Relay DLCI */
fact is that Linux ACKNOWLEDGES it as a legitimate ARP type, but it's
content is probably what drives it nuts. maybe it has something to do with
RIP2 or some other routing protocol? I don't want to enable that, and
AFAIK it's not a low-level protocol that uses ARP broadcasts... I'll leave
that to the netmedia experts (I hope they help me with this poser better
than they did with the last one :-))
