Configuration of ECFM on Provider bridges

MAC Address of ports on the bridges is of form 00:0m:02:03:04:0n, where m is the bridge number and n is the port number for that bridge in this sample topology.

The above figure depicts a topology for a Provider bridged network consisting of two customer bridges (Switch1, Switch5), two provider edge bridges (Switch2, Switch6), and four provider core bridges (Switch3, Switch4, Switch7, Switch8). Maintenance Points (MEP/MIP) are configured at the same MD Level and VLAN shown by the color code, at the same type of the bridges. For example, the blue color represents MEPs configured at Level 7 and VLAN 2 at customer bridges (Switch1 and Switch5).

Connectivity is checked between all the bridges (Switch1 to Switch 8) through Continuity Check Protocol. A Link failure is intentionally incorporated at P2 of Switch 5. Loopback and Linktrace protocols are then used for verification and isolation respectively. AIS and LCK are used for fault suppression.

Connectivity at customer bridges is provided through two Provided Edge bridges and four Provider Core bridges. Service is provided to the Customer through the Provider Network and to Provider Network through the Provider Core Network. Service is provided through the configuration of CFM entities at the respective MD Level on customer and provider bridges.
