ppp encapsulation

nanga

Basic goal : set up a ppp encapsulation on 2 routers and ping them

Background
1) using a simulator
2) Have 2 routers with S2/0 on both the routers with a serial cable connected
3) Router 1 hostname is ATL, Router2 hostname is SNQ

Config :
configured
1) hostnames on both routers
2) ppp encapsulation
3) configured the required username (remote router) and password(same password)
3) did not configure authentication chap pap
4) configured ip address
5) Router1 is DCE .....clock rate as 9600

....but still the line is up and protocol down...is there anything that I am missing.

Troubleshooting :

LCP is closed....that means the keep alives are not been received
1) checked the clock rates on DCE side
2) no username password...hence no config issues on authentication.
3) ppp encapsulation is used on both the routers.

if this is your second router ...

SNQ#show int s2/0
Serial2/0 is up, line protocol is down (disabled)

Internet address is 10.10.10.2/24
MTU 1500 bytes, BW 128 Kbit, DLY 20000 usec,

might want to configure the connecting DTE serial interface for PPP

nanga

bingo....thanks for the reply.....daam it i do remember I had configured that as ppp....anyways thanks for the help

welcome

note: might as well set the authentication chap pap while your at it...
