Can I subnet my network like this ?

[Max Clark]

The only real concern is if you are using cisco routers in this equation. If
so, make sure you enable ip-subnet-zero in the config.

Subject: Can I subnet my network like this ?


Hi, all

   I would like to verify my knowledge
by building the network like below but not
sure whether it's impossible for subnetting
like this - say, from Gateway no2, is divided
to 172.16.0.0/16 and 172.17.0.0/16 subnet.

   I heard that it isn't recommend or
impossible (not sure again) to use FIRST or
LAST subnet in the allocated IP address pool,
is it?

  Section no.1 is existed and I own the Gateway no.2.
My plan is enable NAT on it by following the
instruction in FreeBSD handbook. Any comments are
welcome.

       | if_2 = 10.0.0.1                   |

  |---------------| if_2 = 172.16.0.1/16   | section 2
  | Gateway no.2  |----------------        |
  |---------------|                        |
       | if_3 = 172.17.0.1/16              |
       |                                   |


Thanks in advance,
