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
auto pnet1
iface pnet1 inet dhcp
    bridge_ports eth1
    bridge_stp off

iface eth2 inet manual
auto pnet2
iface pnet2 inet manual
    bridge_ports eth2
    bridge_stp off

iface eth3 inet manual
auto pnet3
iface pnet3 inet manual
    bridge_ports eth3
    bridge_stp off

iface eth4 inet manual
auto pnet4
iface pnet4 inet manual
    bridge_ports eth4
    bridge_stp off

iface eth5 inet manual
auto pnet5
iface pnet5 inet manual
    bridge_ports eth5
    bridge_stp off

iface eth6 inet manual
auto pnet6
iface pnet6 inet manual
    bridge_ports eth6
    bridge_stp off

iface eth7 inet manual
auto pnet7
iface pnet7 inet manual
    bridge_ports eth7
    bridge_stp off

iface eth8 inet manual
auto pnet8
iface pnet8 inet manual
    bridge_ports eth8
    bridge_stp off

iface eth9 inet manual
auto pnet9
iface pnet9 inet manual
    bridge_ports eth9
    bridge_stp off

# nat device
auto nat0
iface nat0 inet static
    bridge_ports none
    bridge_stp off
    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
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:21955 errors:0 dropped:0 overruns:0 frame:0
          TX packets:19345 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:44941444 (44.9 MB)  TX bytes:4155467 (4.1 MB)

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
          RX packets:476 errors:0 dropped:0 overruns:0 frame:0
          TX packets:16 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:57955 (57.9 KB)  TX bytes:1208 (1.2 KB)

......

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
          TX packets:132 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:15140 (15.1 KB)  TX bytes:27044 (27.0 KB)

pnet1     Link encap:Ethernet  HWaddr 00:0c:29:5d:66:7b  
          inet addr:10.0.0.128  Bcast:10.0.0.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:fe5d:667b/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:3 errors:0 dropped:0 overruns:0 frame:0
          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。
