Considering the very high price of point-to-point layer 2 enryption devices, I was pondering:
The 1100AHX2 seems to provide a decent 600 Mbps over EoIP/IPSec. If at all possible I would aim to saturate a 1 Gbps link with the encrypted traffic.
What, if any, might be a good way to have 4 or more MT routers provide an encrypted LAN extension (typically over a PBN)?
