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.

/ / start configuring layer 3 switches below

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
