[j-nsp] Problem with an lt- interface

[Mircho Mirchev]

Hi,

I was making more tests on this issue, and discovered that once the
vpls end of the interface is disabled and created again, the tunnel
goes up, but don't pass traffic from other sites on the vpls domain,
only from other interfaces in the same site.

Once the vpls end of the tunnel is added at hierachy level
routing-instance {
    vpls
         {
           protocols {
                vpls {
                     interfaces
                      }
                 }
             }
       }
},
the tunnel goes down and cannot bring it up again by any means

If this can help discovering the problem, it'll be great.
