Configuración de una WAN con HDLC y PPP
En esta entrada explicaré como configurar una WAN mediante 2 protocolos diferentes, PPP y HDLC
CONFIGURACIÓN HDLC
R1#conf terminal R1(config)#ip route 192.168.2.0 255.255.255.0 Serial 2/0 R1(config)#interface loopback 1 R1(config-if)#ip address 192.168.1.1 255.255.255.0 R1(config-if)#exit R1(config)#int Serial 2/0 R1(config-if)#ip address 1.1.1.1 255.255.255.252 R1(config-if)#encapsulation hdlc R1(config-if)#no shutdown R1(config-if)#end R2#conf terminal R2(config)#ip route 192.168.1.0 255.255.255.0 Serial 2/0 R2(config)#interface loopback 1 R2(config-if)#ip address 192.168.2.1 255.255.255.0 R2(config-if)#exit R2(config)#int Serial 2/0 R2(config-if)#ip address 1.1.1.2 255.255.255.252 R2(config-if)#encapsulation hdlc R2(config-if)#no shutdown R2(config-if)#end
CONFIGURACIÓN PPP CON CHAP
R1#conf terminal Router1(config)#hostname Router1 Router1(config)#username Router1 password cisco Router1(config)#ip route 192.168.2.0 255.255.255.0 Serial 2/0 Router1(config-if)#end Router1#conf terminal Router1(config)#interface loopback 1 Router1(config-if)#ip address 192.168.1.1 255.255.255.0 Router1(config-if)#exit Router1(config)#int Serial 2/0 Router1(config-if)#ip address 1.1.1.1 255.255.255.252 Router1(config-if)#encapsulation ppp Router1(config-if)#ppp authentication chap Router1(config-if)#no shutdown Router1(config-if)#end R2#conf terminal Router2(config)#hostname Router2 Router2(config)#username Router2 password cisco Router2(config)#ip route 192.168.1.0 255.255.255.0 Serial 2/0 Router2(config-if)#end Router2#conf terminal Router2(config)#interface loopback 1 Router2(config-if)#ip address 192.168.2.1 255.255.255.0 Router2(config-if)#exit Router2(config)#int Serial 2/0 Router2(config-if)#ip address 1.1.1.2 255.255.255.252 Router2(config-if)#encapsulation ppp Router2(config-if)#ppp authentication chap Router2(config-if)#no shutdown Router2(config-if)#end
CONFIGURACIÓN PPP CON PAP
R1#conf terminal R1(config)#hostname Router1 Router1(config)#username Router1 password cisco Router1(config)#ip route 192.168.2.0 255.255.255.0 Serial 2/0 Router1(config)#end Router1#conf terminal Router1#interface loopback 1 Router1(config-if)#ip address 192.168.1.1 255.255.255.0 Router1(config-if)#exit Router1(config)#int Serial 2/0 Router1(config-if)#ip address 1.1.1.1 255.255.255.252 Router1(config-if)#encapsulation ppp Router1(config-if)#ppp authentication pap Router1(config-if)#ppp pap sent-username Router2 password cisco Router1(config-if)#no shutdown Router1(config-if)#end R2#conf terminal Router2(config)#hostname Router2 Router2(config)#username Router2 password cisco Router2(config)#ip route 192.168.1.0 255.255.255.0 Serial 2/0 Router2(config-if)#end Router2#conf terminal Router2(config)#interface loopback 1 Router2(config-if)#ip address 192.168.2.1 255.255.255.0 Router2(config-if)#exit Router2(config)#int Serial 2/0 Router2(config-if)#ip address 1.1.1.2 255.255.255.252 Router2(config-if)#encapsulation ppp Router2(config-if)#ppp authentication pap Router1(config-if)#ppp pap sent-username Router1 password cisco Router2(config-if)#no shutdown Router2(config-if)#end
