NP交换试题能用GNS3全部模拟吗

之前看到发帖说有些模拟器模拟不了改怎么办{:soso_e202:}

即使是IOU也不能完全模拟

但是IOU还是有很多功能没有实现，参考如下：
NOT SUPPORTED/WORKING ON LAYER 3 IOL (LINUX)
• Multicast with BSR
• NTP Authentication
• PPPoE (working on 12.4, and 15.2(2.3)T)
• Routing loops (IOL will crash)
NOT SUPPORTED/WORKING ON LAYER 2 IOL (LINUX)
• 802.1q Tunneling
• Cisco ISL trunks
• DHCP Snooping
• HSRP address not pingable
• L2 PortChannel (not working on 12.2, working on 15.0)
• L3 PortChannel
• NVI NAT (classic NAT works on TPGEN images only)
• PVLAN
• QinQ
• Routing loops (IOL will crash)
• SPAN/RSPAN/ERSPAN
• VTP version 2 (VTP version 1 works)

模拟思科的交换实验，建议你使用IOU进行模拟
