[j-nsp] Juniper T1 Cross Connect M40

[Erik Sundberg]

Well here is the final config for the t1 cisco-hdlc-ccc cross connect. I had
a couple of people ask me to post it after I got it working.

interfaces {
	t1-0/1/0:11 {
      encapsulation cisco-hdlc-ccc;
      unit 0 {
      	family ccc;
      	}
    	}
	t1-0/1/2:5 {
      encapsulation cisco-hdlc-ccc;
      unit 0 {
      	family ccc;
      	}
    	}
}
protocols {
	mpls {
      	interface t1-0/1/0:11.0;
	      interface t1-0/1/2:5.0;
	}
	connections {
		interface-switch Customer1 {
	            interface t1-0/1/0:11.0;
      		interface t1-0/1/2:5.0;
		}
	}
}

you need to enable mpls on the interfaces it wouldn't commit the config
without it.

Here is how to check the status of it

user at router> show connections
CCC and TCC connections [Link Monitoring On]
Legend for status (St)              Legend for connection types
UN -- uninitialized                 if-sw:  interface switching
NP -- not present                   rmt-if: remote interface switching
WE -- wrong encapsulation           lsp-sw: LSP switching
DS -- disabled                      tx-p2mp-sw: transmit P2MP switching
Dn -- down                          rx-p2mp-sw: receive P2MP switching
-> -- only outbound conn is up
<- -- only inbound  conn is up      Legend for circuit types
Up -- operational                   intf -- interface
RmtDn -- remote CCC down            tlsp -- transmit LSP
Restart -- restarting               rlsp -- receive LSP

      t1-0/1/2:5.0                      intf  Up
