Re: MPPE - The link comes up but unable to send data

Hi Jorge,

Your config is correct only . Please configure USERNAME and password . Let
me know if works.

*R4*
*===*

R4(config-if)#do sh run int se0/1
Building configuration...

Current configuration : 178 bytes
!
interface Serial0/1
 ip address 155.29.45.4 255.255.255.0
 encapsulation ppp
 ip ospf 1 area 0
 clock rate 64000
 ppp encrypt mppe 128 passive
 ppp authentication ms-chap
end

R4(config-if)#do sh run | in user
*username R5 password 0 cisco*

*R5*
*===*

R5(config-if)#do sh run int se0/1
Building configuration...

Current configuration : 179 bytes
!
interface Serial0/1
 ip address 155.29.45.5 255.255.255.0
 encapsulation ppp
 ip ospf 1 area 0
 clock rate 64000
 ppp encrypt mppe 128 required
 ppp authentication ms-chap
end

R5(config-if)#do sh run | in username
*username R4 password 0 cisco*

*R5*(config-if)#do pi 155.29.45.5

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 155.29.45.5, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/48/180 ms
*R5*(config-if)#*do pi 155.29.45.4*

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 155.29.45.4, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/211/332 ms
