MLAG with Provider Bridging Configuration
This chapter contains sample MLAG with Provider bridging configuration.
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.
MLAG (also called DRNI, Distributed Resilient Network Interconnect) expands the concept of link aggregation so that it provides node-level redundancy by allowing two or more nodes to share a common LAG endpoint. MLAG emulates multiple nodes to represent as a single logical node to the remote node running link aggregation. As a result, even if one of the nodes is down there exists a path to reach the destination through the other nodes.
Note: For MLAG with PB, use provider rstp edge bridge on TOR (PEB) nodes and LEAF (PB) node.

Validation
Validation commands are : show mlag domain summary , show mlag domain details, show ether-channel summary, show bridge, Show mac address-table bridge <bridge-id>, show cvlan registration table bridge <bridge-id>
 
For below show mac table output sending cvlan 100 traffic from SWITCH to LEAF, for which TOR nodes add svlan 1000 and egress same to LEAF and LEAF ixia also receives double tag.
