I’m on the road. I’ll try it when I get some time and equipment to test on.
If someone else has any suggestion in the meantime, feel free to contribute.

No, that filters network 199.16.1.0-199.16.7.255 on the first ACL and 199.16.8.0-.255 on the second ACL - not just even networks.

Unless I misunderstood the requirement, that should cover it.

Hi all,

But 199.16.1.0 0.0.7.255??? this is actually 199.16.0.0 0.0.7.255 and the zero
subnet has to be filtered.

BR,

Lora

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
