Huawei configures VRRP

Experiment:

Ideas and steps:

1.sw1 creates vlan10 vlan20 vlan30 vlan40, and each port joins its own vlan

0Accord0According to the trunk mode

two。 Configure on sw2:

0DB 0ax 5 is the trunk mode, create vlan10 20 30 40

Configure vlanif10 ip:192.168.10.254/24

Vlanif20 ip:192.168.20.254/24

Vlanif30 ip:192.168.30.254/24

Vlanif40 ip:192.168.40.254/24

The virtual gateway 192.168.10.250 configured with vlanif10 has a priority of 150

Vlanif20's virtual gateway 192.168.20.250 has a priority of 150

Vlanif30's virtual gateway 192.168.30.250

Virtual Gateway 192.168.40.250 of vlanif40

3. Configure on sw3:

Trunk mode, create vlan10 20 30 40

Configure vlanif10 ip:192.168.10.253/24

Vlanif20 ip:192.168.20.253/24

Vlanif30 ip:192.168.30.253/24

Vlanif40 ip:192.168.40.253/24

Configure the virtual gateway 192.168.10.250 for vlanif10

Vlanif20's virtual gateway 192.168.20.250

Vlanif30's virtual gateway 192.168.30.250 has a priority of 150

Vlanif40's virtual gateway 192.168.40.250 has a priority of 150

Verify:

Vlanif10 20 is master routing in sw2 configuration

Vlanif30 40 is master routing in sw3 configuration

Key points:

VRRP: (public agreement)

Running between multiple routers

You can virtualize one or more gateway IP addresses (virtual routers)

So as to realize the interworking between different network segments of the intranet.

The working process of VRRP:

1. The interaction between "multiple" routers running VRRP through the VRRP message, thus selecting

The best router, as a Master router, will be used for this device in the future.

To forward the packet

2. There is only one Master router; other routers are called backup routers.

3. At the same time, Master and Backup routers will produce a virtual router, that is, a

Virtual IP address

VRRP configuration commands:

1. Enter the gateway port

2. Configure VRRP virtual IP address

3. Modify the priority of the primary router

Interface fas0/0

Vrrp vrid 1 virtual-ip 192.168.10.250 / / enable VRRP and configure the virtual gateway IP

Vrrp vrid 1 priority 110 / / configure the priority of the VRRP master device

The default is 100

4. Verify, test, save

Show vrrp

R1/R2:

Debug ip icmp

PC:

Ping 192.168.10.250

R1/R2:

Router#write

HSRP:hot standby route protocol, dual Hot backup Protocol; [Cisco Private Protocol]

The same function:

The command is slightly different:

Interface fas0/0

Standby 1 ip 192.168.10.250 / / enable VRRP and configure the virtual gateway IP

Standby 1 priority 110 / / configure the priority of the VRRP master device

The default is 100

Standby 1 preempt / / enable the preemption function of the HSRP of the device

-

HSRP Link tracking:

"external link" tracking technology in HSRP to ensure that when the gateway device goes to the outer network, there is a problem.

In the future, the internal HSRP can be sensed immediately, thus lowering its HSRP priority.

To ensure that standby routers in the HSRP group can be quickly upgraded to active routing

Realize the forwarding of data packets.

Configuration implementation:

Interface gi0/0

Standby 1 ip 192.168.10.250

Standby 1 priority 150

Standby 1 preempt

Standby 1 track gi0/1 100

/ / the HSRP under this port monitors the link status of gi0/1 at all times.

If the status changes to down, the HSRP that the port sends out

The priority in the message is reduced by 100 to 50.

=

VRRP: (Huawei configuration command)

R1: (master router)

Interface gi0/0/0

Vrrp vrid 1 ip 192.168.10.250

Vrrp vrid 1 priority 150

Vrrp vrid 1 track interface gi0/0/1 reduced 100

/ / track the status of port gi0/0/1, if down

It is reduced by 100 and the priority is changed to 50.

R2: (backup router)

Interface gi0/0/0

Vrrp vrid 1 virtual-ip 192.168.10.250

Restore the port to the default configuration:

Cisco:

Router (config) # default interface fas0/0

Huawei:

[sw] clear configuration interface fas0/0

/ / the command for the port will be cleared, and the port will enter the "off" state.

If you want to use it again, you must have "undo shutdown"
