![]() I have GNS3 running (never used it before) and it is very cool for old IOS routers, but I am reading conflicting info (perhaps due to changes over time) on how well either VIRL alone or GNS3 with IOSVL2 and IOSV元 images from VIRL can emulate catalyst switch functionality (especially 元). All private fiber or microwave, no VPN or encryption involved at this point, no ASA's (we will have some but that's a separate and easily handled aspect) and no IOS routers just the 元 switches. ![]() ![]() So the closer to functional equivalency the better. The plan is to use EIGRP and 元 routing mostly, but during the transition have to bridge a lot of legacy VLAN's (and/or tunnel them) we also want to experiment with various configurations of two microwave rings involved (easily simulated by an L2 switch in various configurations) and how those interact with the p2p fiber connections used for a second or third redundancy. I am perfectly happy to get the VIRL subscription from Cisco, my question is not about cost, but I am unable to tell if it solves my problem, either alone or with GNS3, and would prefer to avoid wasting the time if the answer is "not a good approach". I would like to simulate or emulate the design of a replacement network which will be 元 routed (the easy part) but will have a lot of simultaneous L2 VLAN bridging (or tunnels) to accommodate the transition from the existing network.
