The MAC Address of jump, purpose IP address, the MAC Address of next-hop.Wherein IP address is always maintained at constant, and MAC Address is each
It can be all changed when forwarding.That is IP denotes inception point and terminus, and MAC Address indicates our station and the next stop.I.e. A- >
In B- > C- > D structure.If A wants to send data packet to D, need to be written the IP address of A, the MAC of A, D in the packet
IP address, the MAC Address of B.At this time data packet can receive data packet by B and be then forwarded to C, this data packet is the IP of A
Location, the MAC Address of B, the IP address of D, the MAC Address of C so repeat.
In addition, usually ARP protocol is the corresponding relationship for inquiring other IP address of equipment and MAC Address, and gratuitous ARP
(gratuitous ARP) is then the MAC Address that one data packet of system active transmission inquires the machine IP.There will not be machine at this time
This ARP inquiry is responded, but when other equipment in local area network receive this data packet, will use the source IP of this data packet kind
Address and source MAC update oneself ARP table.An ARP data packet is constructed, source IP address is for Service Gateway IP
Location, source MAC are storage gateway MAC address (because Service Gateway already off), send its allowed in local area network
Its equipment updates the ARP table of oneself.
Correspondingly, can refer to Fig. 3 b, service plane idiographic flow schematic diagram is switched back into for memory plane, comprising:
Step A2, the IP of original eth0 is deleted from br1, and eth0 is deleted from br1.
Step B2, ARP proxy function is closed in triggering.
Step C2, the ARP table that gratuitous ARP updates all virtual machines on br1 is sent, the MAC Address for storing gateway is business
The MAC Address of gateway；
That is the source IP address of the ARP IP address (i.e. the gateway IP of virtual machine) that is tor1, MAC Address are the MAC of tor1
Address.
Step D2, eth1 is re-added on br1 and sends the new MAC Address of gratuitous ARP notice br1.
Notice memory plane MAC Address is service plane MAC Address.
Step E2, service plane IP address is tied on br1；
Step F2, restore eth0 network interface card IP address；
Step G2, restore the routing that original outgoing interface is eth0；
The IP of original eth0 is fitted on eth0 again, restores the routing that original outgoing interface is eth0, after route recovery,
System routing is consistent with preservation when machine tool (i.e. host) rigid starting up.
Step H2, refresh host MAC table.
Empty host arp cache, it is therefore an objective to allow br1 interface to acquire new gateway MAC address immediately, i.e. tor1's
MAC Address.
