桥接模拟的设备到网卡
1、EVE的两个网卡。
2、root@eve-ng:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
iface eth0 inet manual <<<<<<<<<<这是我们的管理接口，是VMnet8
auto pnet0
iface pnet0 inet dhcp
bridge_ports eth0
bridge_stp off
# Cloud devices
iface eth1 inet manual <<<<<<<<<<<这是我们的桥接接口，选择的是VMnet1这个网卡

address 169.254.254.1
netmask 255.255.255.0
up service udhcpd restart
3、root@eve-ng:~# ifconfig
......
pnet0 Link encap:Ethernet HWaddr 00:0c:29:5d:66:71
inet addr:10.1.2.128 Bcast:10.1.2.255 Mask:255.255.255.0
inet6 addr: fe80::20c:29ff:fe5d:6671/64 Scope:Link

......
4、重启网卡（因为之前pnet1是Manuel的，可以看到修改为了dhcp）
root@eve-ng:~# /etc/init.d/networking restart
Restarting networking (via systemctl): networking.service.
此时再使用ifconfig可以看到pnet1已经获取到了IP地址。
pnet0 Link encap:Ethernet HWaddr 00:0c:29:5d:66:71
inet addr:10.1.2.128 Bcast:10.1.2.255 Mask:255.255.255.0
inet6 addr: fe80::20c:29ff:fe5d:6671/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:145 errors:0 dropped:0 overruns:0 frame:0

RX bytes:15140 (15.1 KB) TX bytes:27044 (27.0 KB)
pnet1 Link encap:Ethernet HWaddr 00:0c:29:5d:66:7b

inet6 addr: fe80::20c:29ff:fe5d:667b/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

TX packets:11 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:704 (704.0 B) TX bytes:1402 (1.4 KB)
5、测试
此时可以在EVE中桥接。
选择Network
然后选择一个Cloud，只要同一个网段即可通信。
我们使用该Cloud和C7206的接口E1/2连接.
接下来在C7206上配置IP地址。
Router(config)#int e1/2
Router(config-if)#ip add 10.0.0.129 255.255.255.0
Router(config-if)#no shu
Router(config-if)#end
此时我们来ping pnet1和Vmnet1
Router#ping 10.0.0.128
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.128, timeout is 2 seconds:
.!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/12/16 ms
Router#ping 10.0.0.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.1, timeout is 2 seconds:
.!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/13/20 ms
可以看到已经没问题。
