Hi,
Here're the config.s of two LECs (small s) not using a LECS. Don't get too
excited, as far as I'm aware, the LES still needs to register with it,but...
Look at the output of 'show lane client' on both boxes - notice the zeros
0000000000000000 where it says TYPE configure (configure direct svc from LEC
to LECS (usually)). The LEC is going straight to the LES.
Note on the second LEC (R14) I didn't specify a BUS (the LES supplies the
address for that).
Now, tantilizingly, in Caslow book (pg.270) he says, 'A LECS is optional.It
is an administrative tool.'
Interaction between the LES & LECS in my scenario is I believe for security
(remember restricted elans!).The LES checks with the LECS to see if the LEC
is allowed to join (could be wrong).
