Routing in TEN-34 MANs
Every University, R&D MAN connected to
TEN-34CZ (AS 2852) - strict AUP !!!
CESNET (AS 1902, AS 2605) = commercial network open to everybody
CESNET used for backup of TEN-34CZ
Local peering in every MAN between TEN-34CZ & CESNET networks
No transit of commercial packets through TEN-34CZ allowed
