3 Cisco routers. I need to block telnet and ping on the loopback ip address, but able to do everything else. Also I should be able
to ping and telnet through the Ethernet IP address. I’m using router rip
version 2. I have the 3 routers connected by serial and Ethernet.
> Router A IP
> 192.68.1.1
> 172.32.2.1
> Router B IP
> 192.68.1.2
> 172.32.2.2
> Router C IP
> 192.68.1.3
> 172.32.2.3
> I already used the following Access list
> Access-list 101 deny 23 any any
> Access-list 102 deny ICMP any any echo
> Access-list 102 deny ICMP any any echo-reply
> I applied it at the loopback. I was able to block telnet but not the
ping.
> Any suggestions?
