ok ok… i was a little confuse …because I was reading …“troubleshooting ip routing protocol”:
in one page it explains that if in one router is configured Rip (1o2) and its neighbor has on interface face on it an ACL writted in that way…We have to pay attention that broadcast address o multicast address are permitted…
Another thing: the difference between the keyword TCP/UDP… and IP in extended ACL:: if its writted permit/deny TCp oUDP … the router match the application specified by eq keyword, right??
And IP match all application that use TCP,UdP plus per example icmp,eigrp…ecc…(all that "application that encapsulate directly in IP, like eigrp, icmp for example…right??
