local-proxy-arp enable命令用来开启本地代理ARP功能。
【定义及作用】 本地代理ARP,以网关自身的MAC回应本网段的IP地址的ARP请求,用于二层端口隔离时,同一网段的客户之间能够通信。 参考配置 int vlanif 4000 local-proxy-arp enable
You can use local proxy-arp in a multi-tenant environment when other tenants share the same subnet. You break the L2 interconnectivity by using private vlans. So then if you want to have some controlled interaction then you enable local proxy arp and configure the appropriate acl's on that...
you have to break it at layer 2. you can use local proxy-arp in a multi-tenant environment when other tenants share the same subnet. you break the l2 interconnectivity by using private vlans. so then if you want to have some controlled interaction then you enable local proxy arp and con...
NOTE:Internet control message protocol (ICMP) redirects are disabled on interfaces on which local proxy ARP is enabled. To enable local proxy ARP, you must first enter VLAN context, for example: Then enter the command to enable local proxy ARP:...
In addition, the local device may fail to send ARP packets in time due to the replication of a large number of packets, which may lead to ARP learning failures. Therefore, do not configure too many VLANs on an interface. Example # Enable inter-VLAN proxy ARP on VLANIF 10. <HU...
如果ARP请求是从一个网络的主机发往同一网段却不在同一物理网络上的另一台主机,那么连接它们的具有代理...
When C1 wants to send something to C3 it will ask all his neighbours on local LAN segment where is the 192.168.50.50 by sending ARP request in form of broadcast. If the router R7 responds to this ARP request with his own MAC address of the local interface (00:00:0c:ab:cd:a1), C1...
Local-proxy-arp can't be used anymore, because each of the routers will quickly learn each other's MAC address for the client IPs, causing loops. On the other hand some services, like DHCP, try to verify, that free IP addresses are unused, by arping for that IP. Any generic local-...
Run the arp-proxy enable command to enable routed proxy the ARP on the interface. Run the ping 192.168.2.2 command on PC1 to ping the IP address of PC2. Then, run the arp -a command on PC1. The command output shows that the MAC address corresponding to the IP address of PC2 is ...
