Have any EXOS technology can be apply to extend Layer 2 in different Data Centers across Layer 3 network (OSPF)? <BR /> <BR /> Thanks<BR /> <BR /> Wed, 24 Feb 2016 18:25:00 GMT https://community.extremenetworks.com/t5/network-architecture-design/layer-2-extension-across-layer-3-network-jumbo-frames-and-mpls/m-p/15350#M2343 KeN_Chung 2016-02-24T18:25:00Z RE: Layer 2 extension across Layer 3 network (Jumbo Frames and MPLS is not allowed) https://community.extremenetworks.com/t5/network-architecture-design/layer-2-extension-across-layer-3-network-jumbo-frames-and-mpls/m-p/15351#M2344 Hi Ken,<BR /> <BR /> As far as I know MPLS/VPLS and VMAN are the only options that EXOS currently support to create an L2 tunnel over L3 network.<BR /> Wed, 02 Mar 2016 02:14:00 GMT https://community.extremenetworks.com/t5/network-architecture-design/layer-2-extension-across-layer-3-network-jumbo-frames-and-mpls/m-p/15351#M2344 Henrique 2016-03-02T02:14:00Z
