Hi,
This is a usefull and pratical technique to know, having the lane client
hardcoded with the LES address. I have seen several customers do this so
that anyone cannot just put a LEC on the network and get properly
configured and attached to the ELAN. Saves having to do
lots of filtering. Some people just change the address of the LECS away
from the well-known, but I like this solution better.
