[comp.protocols.appletalk] FastPath IP-Subnetting.

edb@fai.UUCP (Edward Bunch) (03/29/89)

I ran across what *might* be a misconfiguration of a FastPath using Kinetic's
Subnetting scheme. I am using shift 5, mask 11 which gives me something just
over 30 internet addresses in each appletalk subnet. Normally I have been
giving the ethertalk internet address something outside the range of numbers of
the subnet I was setting up. But E's looking much like F at times, I used
one of internet addresses in the range of the subnet.

( What I thought I did)
#128.1.190.74 	granny		#appletalk gateway

( What I did )
#	G.N. 05 0B 8001BF40     8001BF4A
                                     ^----------Should have been an E.
#	      5 11 128.1.191.64 128.1.191.74    (ie. 128.1.190.74)
#	Apple Talk Zone: granny
#	         Net#  : 1530
#	Ethernet Zone  : navel
#	         Net#  : 1521
#	Valid I/P @    : 128.1.191.64-95
#	128.1.191.64		gateway from localtalk side.
#	128.1.191.65		mac1
#       128.1.191.66		mac2
( got cha )
#	128.1.191.74            oops can't use this one for a mac.

Can anyone see any reason not to do this. It seems to me that it would simplify
my records of used @'s if the FP on both sides and the mac @'s were all in one
place. Setting this up on purpose I would use 128.1.191.65 for the gateway from
ethertalk side; 128.1.191.66 would be the first mac.
