Hi, I have a Cisco 3620 and trying to enable ISL encap on that (VLAN communication). but it seems there is no such command available on this router. Martin told that 12.0(28c) doesnt support it, so Can I upgrade the IOS on this box and what would be the best version to go with. Thanks in advance-Rob
