[j-nsp] L2VPN Site id confusion

[David water]

In L2VPN BGP based we need the unique site id for each and every connected
CE device on PE router as label will be calculated on the based of it. But I
am bit confuse with the remote site id configuration, is it used in cross
connect or how does it work with L2VPNS?

To calculate outgoing inner label formula is (local-site-id +
remote-label-base – remote-label-offset) correct me if I am wrong?
