Hi,
See below:
199.16.1.0 ----199.16.00000001.0
Wildcard:
0.0.6.255 --C 0.0.00000110.0 (0 bexact match, 1 b donb care)b&so, with this wildcard mask you say that the last bit should be always zero..(no even subnets)
BR,
Lora

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 b 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 <http://150.1.1.1/> 255.255.255.0 <http://255.255.255.0/>
R2:
Eth1/0
Ip add 150.1.1.2 <http://150.1.1.2/> 255.255.255.0 <http://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
