What is dual uplinks? My topology is linear. Gi0/1 goes to the South neighbor in the chain, and Gi0/2 goes to the North neighbor in the chain, like in ftp://ftp.sibptus.ru/pub/vas/Screenshot-306.png > It doesn???t know > that they both go to the core layer. Sometimes there is more than one link between two neighboring switches, STP takes care of them. Other than that, the topology is linear. I can even make it totally linear by manually disabling a couple of redundant links. > One could be a downstream > switch as far as VTP is concerned. Sometimes there is more than one link between two neighboring switches, STP takes care of them. Other than that, the topology is linear. I can even make it totally linear by manually disabling a couple of redundant links. I expect that if a vlan is being used only on one or two switches on one end of the chain, it should be pruned from the rest of the chain. But it is not happening. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN sip:[email protected] _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
