(Ring, Mesh, Star)<BR /> <BR /> Have you considered Link Aggregation, MLAG, or EAPS?<BR /> <BR /> Thu, 28 Jan 2016 01:31:00 GMT Dorian_Perry 2016-01-28T01:31:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/in-network-without-vlan-we-want-to-implement-loop-based-links/m-p/16400#M335 We have 1 L3 switch and 3 L2 switch with OFC links. We want to implement a redundancy in network so that if there is any cable cut in between the other links should be connected. We tried STPD but it is not working. There is no VLAN, we have only Default Management VLAN1.<BR /> <BR /> Thu, 28 Jan 2016 01:13:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/in-network-without-vlan-we-want-to-implement-loop-based-links/m-p/16400#M335 Sengut_vp 2016-01-28T01:13:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/in-network-without-vlan-we-want-to-implement-loop-based-links/m-p/16401#M336 Hi Sengut,<BR /> <BR /> What is the topology of the network?
