H3C Three-Layer Aggregation

1. Configuration steps

1. The switch needs to enter the interface and change the interface to Layer 3 mode. (Routers do not need to change, the default router mode)

2. Create an aggregated interface group

3. Add the interface to the aggregation group

4. Enter the aggregation group view to configure the ip

Note: The switch interface default layer two mode, you need to change the interface to layer three

2. Configuration commands

2.1 R1 switch configuration

[R1] int range GigabitEthernet 1/0/1 #Enter interface 1
[R1-GigabitEthernet1/0/1]port link-mode route #Change the switch interface mode to Layer 3 mode
[R1]Int route-aggration 3 #Create Layer 3 aggregation interface group 3
[R1-if-range]port link-aggregation group 3 #Add interface 3 to the aggregation group
[R1]Int route-aggration 3 #Enter aggregation group view
[R1-Route-Aggregation3]Ip address 192.168.1.1 24 #Configure IP for the aggregation group

2.2 R2 routing configuration

<H3C>sys #Enter configuration view
[H3C]sys R2 #Change the name
[R2]int route-aggration 3 #Create Layer 3 aggregation interface group 3
[R2]quit  
[R2]int range GigabitEthernet 0/1 #Enter interface 1
[R2-if-range]port link-aggregation group 3 #Add interface 1 to aggregation group 3
[R2]quit
[R2]int range GigabitEthernet 0/2 #Enter interface 2
[R2-if-range]port link-aggregation group 3 #Add interface 2 to aggregation group 3
[R2]quit
[R2]Int route-aggration 3 #Enter aggregation group view
[R2-Route-Aggregation3]Ip address 192.168.1.1 24 #Configure the aggregation group IP and mask (24 is 255.255.255.0)
