Symmetric Topologies
In symmetric topologies, traffic beyond the ML edge devices (CO and CPE) is forwarded
unchanged. The symmetric topology matches with P2P installation needs, where ML NE is
used as a media converter only or where Customer and Provider site L2 plane is flatly
merged.
The following configurations of the ML link work for symmetric topologies:
 HUB;
 TUNNELS;
 Transparent for ANY Customer traffic;
 Transparent for Untagged Customer traffic;
 Transparent for Specified Tagged Customer traffic (CE-VID filtering);
HUB configuration is applicable in any deployment, providing VLAN-unaware (802.1D)
behavior on each NE. Management traffic in this configuration can be either VLAN-tagged
or VLAN-untagged, as desired.
TUNNELS configuration, which is suitable for P2P deployments, providing transparent
(frames are unchanged beyond the ML systems) and separate (each port is protected from
other ports by an internally applied VLAN) tunnels through the ML between the
10/100/100BT/FX Port connected to the PAF-2BaseTL Port. Management traffic in this
configuration can be either VLAN-tagged or VLAN-untagged, as desired. There are 2
different configurations that can achieve Transparent behavior of service traffic, one allowing
in-band and out-of-band management (with some limitations regarding Service Traffic),
another allowing out-of-band management only (without limitations on Service Traffic).
