Junos OS

Greetings,

 

I'm still cutting my teeth on the JUNOS and I'm having a difficult time seeing what I'm doing wrong trying to hook up these two routers to each other.

 

I have 2 J2320's with the T1 interface cards in them and I'm attempting to setup in any sort of fashion for a demo.  I choose Frame-relay to start with because I just figured it would be the easist, but I'm willing to use whatever works to make these cards talk to each other.

 

Router1 configuration snip:

 

interfaces {
....
	t1-1/0/0 {
		no-keepalives;
		mtu 256;
		encapsulation frame-relay;
		t1-options {
			time-slots 1-24;
			buildout 0-132;
		}
		unit 0 {
			dlci 200;
			family inet {
				address 192.168.200.1/30
			}
		}
	}
}

 

 

 

Router2 configuration snip:

 

interfaces {
....
	t1-1/0/0 {
		no-keepalives;
		mtu 256;
		encapsulation frame-relay;
		t1-options {
			time-slots 1-24;
			buildout 0-132;
		}
		unit 0 {
			dlci 200;
			family inet {
				address 192.168.200.2/30
			}
		}
	}
}

 

Try as I might, I can't even get any sort of connectivity to show and I know that I've got to be missing something stupid, but I've tried every possible configuration I can think of from the web and command line interfaces and I'm still getting nothing.

 

#t1
#config

Try setting one side to dce mode.

 

  set interface t1-1/0/0 dce

 

If that doesn't work, could you send the output of 'show interface extensive' for both interfaces.

Ben

Tried setting the dce on router2, didn't resolve it.  I'm typing in the interface extensive now.

 

Also, while I was back there, I also tested my cross over cable just to make sure it was good and maybe hope for a stupid quick solution ... sadly, the darn cable is good 🙂

This router has LOF/LOS alarm.  That means it is a physical issue.  When you say "Crossover" cable, are you trying to use an Ethernet crossover cable?  If so, that will not work for a T1.

 

For T1, you need to cross pins 1&2 with pins 4&5, respectively.

Holy crap I'm a moron.  I didn't even look to make sure I grabbed the right one out of our lab.  Sure enough, that was the problem.
