When you mistakenly type the wrong command at the Router# prompt the router does a DNS lookup which takes about 20 seconds. Which command can you enter to prevent the router doing this in future?

Write out a config to permit only the below MAC address to pass traffic through a port on your switch. in another way writhe a confrigation which permit only mac address trfaic through a port of your switch

let there are three switch and there are 3 ree valn craed on each switch that is vlan 2 on first switch valn 3 on 2nd switch and vlan 4 is cretaed on switch 3 i have implemnted intervlan routin through ciso switchses. the router is conected through its fa0/1 port by one switch and and the two switch are trunked with each other now question is that we want to comuniacte betwwen vlan but does alse want that only vlan 2 is allow to access internet (ISP)which is conected through s0 interface of router.and no any vlan can access that internet.what should be solution.

Write an access list line which will deny node 20.0.2.1 to anywhere on your network using DNS via UDP. Don't worry about the other access list lines.

You have OSPF traffic flooding your network via one of your router interfaces. Write the access list line that will deny all ospf traffic. Don't worry about the other lines of the access list.

How to see the running-config & startup-config infor from global configuration mode.

Hi Guys I am facing one problem while configuring PAP over Point to Point links. Configuration scenario is like this. ROUTER 1: (Hostname – R1) R1(config)#username R2 password CCNA2 R1(config)#interface serial 1/1 R1(config-if)ip address 10.0.0.1 255.0.0.0 R1(config-if)#lock rate 64000 R1(config-if)#encapsulation ppp R1(config-if)#ppp authentication pap R1(config-if)#ppp pap sent –username R1 password CCNA1 R1(config-if)#no shutdown ROUTER 2: (Hostname – R2) R2(config)#usename R1 password CCNA1 R2(config)#interface serial 1/1 R2(config-if)#ip address 10.0.0.2 255.0.0.0 R2(config-if)#encapsulation ppp R2(config-if)# ppp authentication pap R2(config-if)# ppp pap sent –username R2 password CCNA2 R2(config-if)#no shutdown Now problem is that, after configure the command “ppp authentication pap” the “Line protocol” status goes down on each router. But when I disable this command using “no ppp authentication pap”, the “Line Protocol” status goes up. What could be the problem, can anyone explain it plzzz….!!! Thanks in Advance…!! Shahin..
