Dear Community.We have a network basically configured with Catalyst 3560G/E/X, full feature, that is vrf-lite, ospf.The "problem" occured when I had the first network-ring configured, and one port was blocked by spanning-tree in this ring-structure.A...
Dear forum.I have a layer 3 network, using ospf, no layer 2 between my C3560 devices, please take a look at the attached pdf.I also have two layer 2 devices, that I would like to connect to this network (these are two Allied Telesyn AT-8024, simple L...
HiWe want to implement QoS in our network. Have read "a few" doc's regarding QoS, but still have some unaswered questions.The network is built up with several Catalyst 3560-E, and we are using VRF-lite. The network is divided into several VRFs. Each ...
Hi again GiuseppeOnce again, thanks a lot. I agree, I need to do some reading to fully understand this "problem". I'm not there yet, but hopefully I will be.I do agree that my network is working, but so far, MSTP will manage the redundancy.But so far...
Hi Giuseppe, I really appreciate taking time to give me a helping hand.So, what you are saying, is (I'll try my very best to understand):Each VRF has it's own routing instance and topology, at layer 3. So far I follow.So in my excample I have the ori...
Once again, thanks a lot for your time.I have to say I'm a bit disappointed of the CCIE-guy suggesting this "L3" design!First, the reason for choosing MSTP, is that we still have som old L2-switches in our network, running stp/rstp.Excample, in site ...
Hi Giuseppe.Thanks a lot for your time.First, you don't suggest to use bpdufilter/bpduguard between the 3560s, because this would create bridging loop.My thought was since there are different vlans between each 3560, there will not be a loop, since t...
Hi, thanks a lot for your answer.Yes. was afraid that HSRP was the sollution, because we've been reconfigured our network from a L2 to a L3 network, except from a few L2 devices.I've been struggling with stp/rstp/mst for years, and was hopeing to dro...
