Provider Bridging Configuration
This chapter contains sample provider bridging configurations.
A provider bridged network is a virtual bridged Local Area Network that comprises provider bridges (SVLAN bridges and provider edge bridges) and attached LANs, under the administrative control of a single service provider. Provider bridges interconnect the separate MACs of the IEEE 802 LANs that compose a provider bridged network, relaying frames to provide connectivity between all the LANs that provide customer interfaces for each service instance.

Layer 2 Protocol Tunneling (L2PT/L2CP Tunneling)
L2CP tunneling provides support for tunneling Control plane frames between CE nodes.
When control frames received at CEP port of PE bridge, predefined multicast address (01-00-C2-CD-CD-D0) is used for tunneling the packets across service provider network. If control packets are customer vlan tagged or untagged, then PE bridge will append corresponding service vlan tag to the control packet as per registration table / vlan translation table mapped to the port and send it across the service provider as a data packet.
When tunneled control packet with multicast address (01-00-C2-CD-CD-D0) received on PNP port, the multicast address is replaced with corresponding control packet multicast address and cvlan/svlan removal or updating is done as per registration table / vlan translation table.

New SVLAN 7 is observed on PEB2 At PNP port connected to IXIA-2.
When double tagged traffic of CVLAN 2 and SVLAN 7 is sent from IXIA-2 to IXIA-1:

When you observe the traffic received in IXIA-2, you can observe that new CVLAN 3 and SVLAN 7 tags can be seen. Here the VLAN 2 will be a data packet.
When tagged traffic for CVLAN 3 and SVLAN 7 is sent from IXIA-2 to IXIA-1:

When tagged traffic with CVLAN 2 is sent from IXIA-1 to IXIA-2 with both CTAG and STAG entering provider network and gets translated to new CVLAN and SVLAN as per Case1.

1 6 ge9 6400.6a1e.d9a5 1 300
When the packet is captured at PNP port of PEB2 CVLAN of 3 and SVLAN of 4 is seen.
When tagged traffic for CVLAN 6 and SVLAN 7 is sent from IXIA-2 to IXIA-1:

When traffic is reversed and traffic has both new CVLAN 6 and SVLAN 7 on provider network from IXIA-2, translation to CVLAN 5 and SVLAN 7 happens. Also, captured packets have CVLAN as 2 based on the entry in the cvlan registration table.

Validation for Switchport ethertype
To validate, send tagged traffic of VLAN 2 from IXIA-1.
Now at eth9 of PB2, capture the packets through IXIA-2 and verify that the traffic is received with double tag.
If the 2 tags CVLAN tag 2 will have the TPID of 0x8100 and SVLAN tag 4 will have a TPID of 0x88a8.

Provider Bridging Untagged-pep Configuration
This is a sample configuration to verify functionality to support provider-bridging with untagged-pep feature.
For the below topology configuration,
1. While sending tagged traffic untagged-pep CVLAN 2, it should drop in provider edge bridge.
2. And while sending tagged traffic CVLAN 3 to the provider network, will egress with CVLAN 3 and SVLAN 12 tag and the same CVLAN and SVLAN tag from provider network, will egress with only CVLAN tag
3. And also for untagged traffic to the provider network, will egress with SVLAN 11 tag
