Configuration question

Abrown1966

I have a configuration question

I have router 1 configured as if it is connecting to a frame relay cloud. I have configured the ip address of 172.12.123.1 255.255.255.0 but cannot get the interface in a up state.

I am copying the show int So comand and Appropriate parts of the running config comand.

Is this a physical router? Double check your cabling.

Stupid question but have you tried a "no shut" on the interface?

Abrown1966

It doesn't hurt to ask the obvious. Yes I have tried the no shut down comand.

Toanswer the other post, I cannot physicall access the routers as i connect to them using telnet. I am baffled and have been careful in typing the configuration information.

Okay, what's on the other end of the serial cable? (this is a lab right and not production?)

If he didn't no shut it would have been "administratively down" instead of "down".

Abrown1966,

When you mention that you're "...connect[ing] to the using telnet..." are you talking about an access server connection?

Problem solved.

THe equipment is a rack rental setup. I have acces to three routers with a fourth that acts as a frame relay cloud (no access to this router). Via e-mail to the rack owner, I have learned that the interfaces on router 4 were shutdown. For a while there i thoguht i was loosing my mind.

Thanks for the imput anyway guys/

Glad you got it sorted out, and just think now you know what a "show int" on a router with a physical layer problem looks like (since the other side of the link was shutdown, it's the same as if the cable had been disconnected).
