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_1 = 202.xx.xx.xx
|---------------| |
| Gateway no.1 | | section 1
|---------------| |
| if_2 = 10.0.0.1 |
| ----
| |
| if_1 = 10.0.0.254 |
|---------------| if_2 = 172.16.0.1/16 | section 2
| Gateway no.2 |---------------- |
|---------------| |
| if_3 = 172.17.0.1/16 |
| |
Thanks in advance,
