On sw2, are you using port 12 or 15? Also note that ISL may or may not work. I haven't used GNS3 since 2009, so I'm not sure if the code there supports both. Make sure your trunks are 802.1q.
What happens when you create Vlan567 SVI on sw1 and 2 - can directly attached touters ping those? What do ARP and MAC tables show? -- Marko Milivojevic - CCIE #18427 (SP R&S) Senior CCIE Instructor / Managing Partner - IPexpert :: This message was sent from a mobile device.
