如何优化cisco iou
有网友这么问小编“如何进入cisco路由器设置密码?”，小编在网上搜索了一些资料，供大家参考。
Cisco IOU的优化拓扑图
启动脚本：
mkdir -p /root/CiscoIOU/ccnp
ln -s /root/CiscoIOU/wrapper-linux /root/CiscoIOU/ccnp/router
touch /root/CiscoIOU/ccnp/runlab
chmod +x /root/CiscoIOU/ccnp/runlab
vi /root/CiscoIOU/ccnp/runlab
i
#!/bin/bash
#set -v
cd /root/CiscoIOU/ccnp
export NETIO_NETMAP=/root/CiscoIOU/ccnp/NETMAP
export IOURC=/root/CiscoIOU/iourc
./router -m /root/CiscoIOU/i86bi_linux-adventerprisek9-ms -p 2001 1 — -e 1 -s 1 -n 1024 & sleep 2
./router -m /root/CiscoIOU/i86bi_linux-adventerprisek9-ms -p 2002 2 — -e 1 -s 1 -n 1024 & sleep 2
./router -m /root/CiscoIOU/i86bi_linux-adventerprisek9-ms -p 2003 3 — -e 1 -s 1 -n 1024 & sleep 2

./router -m /root/CiscoIOU/i86bi_linux-adventerprisek9-ms -p 2009 9 — -e 4 -s 4 -n 1024 & sleep 2
unset NETIO_NETMAP
unset IOURC
echo *****ALL ROUTERS STRATED*****

cisco思科IOU/IOL不支持的特性
思科的IOU是很强大，但也并不是万能的，也有一些特性不支持，实验没法做。与GNS3相比，各有千秋吧。
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
