Ping Vrf回环接口
Ping Vrf回环接口
提问于 2017-09-30 16:27:26
我在做一个实验室，这很简单。就像我需要确认一些命令，但我真的很生气。
这是我的实验室。我配置了一个vrf和一个回环接口，并在vrf下应用它。环已从全局表中消失，并插入到vrf表中。因此，我添加了一个静态路由，以便能够从全局表中平移接口。现在，我可以看到全局表中插入的环回接口是静态的，但是我不能点击。
我觉得这里缺少一些愚蠢的东西，因为一切看起来都很好，而且应该能工作。我的路由器配置的输出如下：
ip vrf HQ
rd 30:50

您需要的是从VRF到全局路由表的路由泄漏(您已经做到了)，以及从全局路由表到VRF的路由泄漏。
我假设您的网络图非常简单，如下所示
在R2上，您已经拥有了ip route 1.1.1.1 255.255.255.255 Loopback1。
现在需要另一个静态VRF路由将路由10.0.0.0/24泄漏到VRF总部：
ip route vrf HQ 10.0.0.0 255.255.255.0 10.0.0.1 global在R2上的验证：
R2#show run | i route
ip route 1.1.1.1 255.255.255.255 Loopback1
ip route vrf HQ 10.0.0.0 255.255.255.0 10.0.0.1 global
R2#show ip route | beg Gateway
Gateway of last resort is not set
1.0.0.0/32 is subnetted, 1 subnets
S 1.1.1.1 is directly connected, Loopback1
10.0.0.0/24 is subnetted, 1 subnets
C 10.0.0.0 is directly connected, FastEthernet0/0
R2#show ip route vrf HQ | beg Gateway
Gateway of last resort is not set
1.0.0.0/32 is subnetted, 1 subnets
C 1.1.1.1 is directly connected, Loopback1
10.0.0.0/24 is subnetted, 1 subnets
S 10.0.0.0 [1/0] via 10.0.0.1
R2#ping 1.1.1.1 source 10.0.0.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
Packet sent with a source address of 10.0.0.2
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 68/70/72 ms在R1上的验证：
R1#show run | i route
ip route 1.1.1.1 255.255.255.255 10.0.0.2
R1#ping 1.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/36/64 ms我希望这是有帮助的，并回答你的问题。

您不需要静态路由，只需在vrf中按以下方式进行ping：
