An example is given to explain the detailed usage of the four steps of H3C configuring layer 3 switch.
The four common steps for configuring a layer 3 switch are: dividing the VLAN and describing it; designating a gateway for the VLAN; assigning ports to the VLAN; configuring a routing protocol; and learning these steps will solve all the problems of configuring a layer 3 switch.

The first step in configuring a layer 3 switch: divide the VLAN and describe
Vlan1
Description local-s3600// is used by this switch
#
Vlan2
Description link-to-shanxicentre// Shaanxi Provincial Center
#
Vlan3
Internal use of description link-to-shangjiecentre// Business Center
#
Vlan4
Description link-to-shangdongsuo// Merchant East Office
#
Vlan5
Description link-to-shangnansuo// Merchants South Office
Configure layer 3 switch step 2: set up a gateway for VLAN
#
Interface Vlan-interface 2
Description linktoshanxicentre
Ip address 10.61.242.110 255.255.255.252.Max / provincial center specifies wide area gateway and subnet mask
#
Interface Vlan-interface 3
Description link-to-shangjiecentre
Ip address 10.161.134.65 255.255.255.192 / Business Branch Local area Gateway, Subnet Mask
#
Interface Vlan-interface 4
Description link-to-shangdongsuo
Ip address 10.61.242.113 255.255.255.252.max / Shangdong wide area Gateway, Subnet Mask
#
Interface Vlan-interface 5
Description link-to-shangnansuo
Ip address 10.61.242.117 255.255.255.252.Max / Shangnan wide area Gateway, Subnet Mask
Configure layer 3 switch step 3: assign ports to VLAN
#
Interface Ethernet1/0/2// assigns port 2 of the switch to the provincial center
Description link-to-shanxicentre
Port access vlan2
#
Interface Ethernet1/0/15-24Universe / assign switch ports 15-24 for internal use in the branch center
Description link-to-shangjiecentre
Port access vlan3
#
Interface Ethernet1/0/3// assigns port 3 of the switch to be used by Shang Dong
Description link-to-shangdongsuo
Port access vlan4
#
Interface Ethernet1/0/4// assigns port 4 of the switch to be used by Shangnan
Description link-to-shangnansuo
Port access vlan5
Configure layer 3 switch step 4: configure routing protocol
/ / configure static route (only need to configure one route to the remote device, local self-access)
Ip route 0.0.0.0 0.0.0.0 10.61.242.109 / specify the route from all network segments to Shang Dong
/ / configure reverse routing of layer 3 switches
Ip route 10.161.134.0 255.255.255.0 10.61.242.114
Ip route 10.161.135.0 255.255.255.0 10.61.242.114
/ / configure the reverse routing of the layer 3 switch.
Ip route 10.161.135.0 255.255.255.0 10.61.242.118
Ip route 10.161.136.0 255.255.255.0 10.61.242.118
/ / the provincial center configures layer 3 switches:
Ip route 10.161.242.0 255.255.255.0 10.61.242.110Cash / 242.0 belonging to Shangdong 242.114 and Shangnan 242.118 points to the branch gateway
Ip route 10.161.134.0 255.255.255.0 10.61.242.110 / the internal network segment of the sub-center points to the sub-center gateway
/ / iproute10.161.134.0255.255.255.010.61.242.110
/ / iproute10.161.135.0255.255.255.010.61.242.110
/ / iproute10.161.136.0255.255.255.010.61.242.110
