1. Cada interfaz debe pertenecer a una red diferente, se pueden configurar dos interfaces para pertenecer a la misma red, sin embargo solo UNA podrá estar ACTIVA. Si se configuran dos interfaces con dos IP de la misma red aparecerá este mensaje: “192.168.1.0 overlaps with FastEthernet0/0”. Si se intenta habilitar la interfaz aparecerá el siguiente mensaje:<br />Puebla (config-if)#no shutdown<br />172.16.0.0 overlaps with FastEthernet0/0<br />FastEthernet0/1: incorrect IP address assignment<br />User Access Verification<br />Password: <br />Password: <br />Oaxaca>enable<br />Password: <br />Oaxaca#show running-config<br />Building configuration...<br />Current configuration : 721 bytes<br />!<br />version 12.4<br />no service timestamps log datetime msec<br />no service timestamps debug datetime msec<br />no service password-encryption<br />!<br />hostname Oaxaca<br />!<br />enable secret 5 $1$mERr$ZIvuLWaqZSN.IGTvVO7VE/<br />!<br />ip name-server 0.0.0.0<br />!<br />interface FastEthernet0/0<br /> ip address 172.16.32.254 255.255.224.0<br /> duplex auto<br /> speed auto<br />!<br />interface FastEthernet0/1<br /> no ip address<br /> duplex auto<br /> speed auto<br /> shutdown<br />!<br />interface Serial0/0/0<br /> no ip address<br /> shutdown<br />!<br />interface Serial0/0/1<br /> ip address 10.0.0.2 255.0.0.0<br />!<br />interface Vlan1<br /> no ip address<br /> shutdown<br />!<br />ip classless<br />ip route 11.0.0.0 255.0.0.0 Serial0/0/1 <br />!<br />line con 0<br /> password cisco<br /> login<br />line vty 0 4<br /> password pluma<br /> login<br />!<br />!<br />!<br />end<br />Oaxaca<br />User Access Verification<br />Password: <br />puebla>en<br />Password: <br />puebla#configure terminal<br />puebla#show running-config<br />Building configuration...<br />Current configuration : 739 bytes<br />!<br />version 12.4<br />no service timestamps log datetime msec<br />no service timestamps debug datetime msec<br />no service password-encryption<br />!<br />hostname puebla<br />!<br />!<br />!<br />enable secret 5 $1$mERr$ZIvuLWaqZSN.IGTvVO7VE/<br />!<br />ip name-server 0.0.0.0<br />¡<br />interface FastEthernet0/0<br /> ip address 11.0.0.254 255.0.0.0<br /> duplex auto<br /> speed auto<br />!<br />interface FastEthernet0/1<br /> no ip address<br /> duplex auto<br /> speed auto<br /> shutdown<br />!<br />interface Serial0/0/0<br /> ip address 10.0.0.1 255.0.0.0<br /> clock rate 64000<br />!<br />interface Serial0/0/1<br /> no ip address<br /> shutdown<br />!<br />interface Vlan1<br /> no ip address<br /> shutdown<br />!<br />ip classless<br />ip route 172.16.32.0 255.255.224.0 Serial0/0/0 <br />!<br />line con 0<br /> password cisco<br /> login<br />line vty 0 4<br /> password pluma<br /> login<br />!<br />!<br />!<br />end<br />puebl<br />
