traffic filtering does not work (prefix, access list)

[xdisa]

Hi, everybody!

I'm using FRR 8.3.1 on the opkg package manager. all devices are the same.

The 3 devices are connected as follows:

(R1)eth0 - eth0(R2)e1p1 - e1p1(R3)

on the first device on eth0 address 10.10.10.1/30

on the second device on eth0 address 10.10.10.2/30, on e1p1 address 20.20.20.2/30

on the third device on e1p1 address 20.20.20.1/30

egrp AS 100 routing is up on devices

on the first router I enter the following commands:

ip prefix-list test permit any
ip prefix-list test deny 20.20.20.0/30

ICMP pings come from all three devices. no limit was found for 20.20.20.1. he still gets access to R1

gave commands in conf t:

access-list filter deny 20.20.20.0/30
access-list filter deny 20.20.20.1

ICMP pings come from all three devices. no limit was found for 20.20.20.1. he still gets access to R1

gave commands in conf t:

access-list filter deny any

ICMP pings come from all three devices. no limit was found for 20.20.20.1. he still gets access to R1. although this command completely denies traffic

after which I left the silence and used ip tables

iptables -A INPUT -s 20.20.20.1 -j DROP

and everything worked! ping from 20.20.20.1 fails, that's what I need! but I wanted to do it without using ip tables. I wanted to do it vtish. what is the problem?

I also wrote "permit" rules to the access list and prefix list. it didn't help.

P.S.

I also checked 8.4.3 and 8.5 . doesn't work either. returned to version 8.3.1, because for my tasks it is more stable.

forgot to clarify!

My devices use Debian-based Linux
