The Brocade implementation supports VPLS as described inthe IETF Internet Draft, “draft-ietf-l2vpn-vpls-ldp-05.txt”.VPLS CPU protection shields the management module CPU from being overwhelmed by VPLStraffic that requires CPU processing, such as source-MAC learning, or forwarding ofunknown-unicast or broadcast traffic.MPLS VPLS show commandsThis section describes the show commands that display MPLS VPLS information.show mpls vplsSyntax: show mpls vplsThis command displays information about VPLS instances configured on the device.Brocade# show mpls vplsNum Num Ports Num Peers NumName Id Vlans Ports Up Peers Up VC-labeltest 100 2 3 0 2 0 32show mpls vpls summarySyntax: show mpls vpls summaryThis command displays a summary of VPLS statistics, including the number of VPLS instances,number of VPLS peers, label range size, and maximum size of the VPLS MAC database.Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide 22753-1002426-02
