实验拓扑图如上。
添加了三块虚拟网卡
GNS3 的Cloud桥接三块网卡。
NPTP连接情况
SCRT连接虚拟ASA成功。
ASA的接口信息:
ASA# show int ip b
Interface IP-Address OK? Method Status Protocol
Ethernet0/0 192.168.1.1 YES manual up up
Ethernet0/1 unassigned YES unset administratively down up
Ethernet0/2 unassigned YES unset administratively down up
Ethernet0/3 unassigned YES unset administratively down down
Ethernet0/4 unassigned YES unset administratively down down
Ethernet0/5 unassigned YES unset administratively down down
与路由器R1相连的接口信息:
ASA# show run int e0/0
!
interface Ethernet0/0
nameif inside
security-level 100
ip address 192.168.1.1 255.255.255.0
R1接口信息:
R1#show ip int b
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned YES unset administratively down down
FastEthernet0/1 unassigned YES unset administratively down down
Serial1/0 unassigned YES unset administratively down down
Serial1/1 unassigned YES unset administratively down down
Serial1/2 unassigned YES unset administratively down down
Serial1/3 unassigned YES unset administratively down down
Ethernet2/0 192.168.1.2 YES manual up up
Ethernet2/1 unassigned YES unset administratively down down
Ethernet2/2 unassigned YES unset administratively down down
Ethernet2/3 unassigned YES unset administratively down down
R1 e2/0接口信息
R1#show run int e2/0
Building configuration...
Current configuration : 80 bytes
!
interface Ethernet2/0
ip address 192.168.1.2 255.255.255.0
half-duplex
end
配置基本上是这样,但是在路由器和ASA直连接口互ping 不同。
R1#debug ip packet
IP packet debugging is on
R1#ping 192.168.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:

Success rate is 0 percent (0/5)
昨天搞了一整天,方法试了很多,还是不行,请这里的高人指点一下,谢谢了。
这是ASA的ARP
ASA# show arp
inside 192.168.1.3 0050.56c0.0001 ----------------------------这个地址是虚拟网卡的
这是R1的ARP
R1#clear arp-cache
R1#show arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet 192.168.1.1 6 000c.2905.8f53 ARPA FastEthernet0/0 --------------------ASA e0/0 地址
Internet 192.168.1.2 - c000.0e78.0000 ARPA FastEthernet0/0 --------------------R1 F0/0地址
搞不懂了
