Hi experts,

I am experiencing some problems with the following task:

Two routers , let's say R1 and R2 are connected (media is not important,
let's say it is Ethernet)

R1 Eth1/0---------------150.1.1.0/24------------- Eth1/0 R2

R1:

Eth1/0

Ip add 150.1.1.1 255.255.255.0

R2:

Eth1/0

Ip add 150.1.1.2 255.255.255.0

Routers are running rip and R2 is advertising the following networks to
R1

199.16.0.0/24

199.16.1.0/24

199.16.2.0/24

199.16.3.0/24

199.16.4.0/24

199.16.5.0/24

199.16.6.0/24

199.16.7.0/24

199.16.8.0/24

199.16.10.0/24

199.16.11.0/24

199.16.12.0/24

199.16.13.0/24

199.16.14.0/24

199.16.15.0/24

The task requires by configuring only R1 (not interface level command)
to allow with an ACL with only 2 lines the following subnets:

199.16.1.0/24 - 199.16.8.0/24

I have though a lot of any kind of ACLs but i still haven't come to a
good solution.

Any help will be appreciated,

Thanks,

Lora
