VLAN experiment

One 、 Experimental topics

Two 、 The topology

3、 ... and 、 Experimental configuration

1. establish vlan

2.R1 To configure DHCP

First dhcp enable Turn on the whole dhcp service
And open dhcp Each interface of the service is opened separately
dhcp select global

R1 To configure dhcp

Interface 0/0/0 To configure ip Interface with enable , And as vlan3/4/5/ Of dhcp The server

Configure pool v2

Configure pool v3

Configured dhcp result

A subinterface 0/0/0.1 As vlan2 Of dhcp The server

3. Whether the switch interface is configured with labels

LSW1

To meet the requirements
E 0/0/1 Use hybrid interface mode , allowed v2 The label of , It is not allowed to bring v3 to 5 The label of


E 0/0/1 Use hybrid interface mode , Allow all vlan With label

E 0/0/3 Because the configuration is required to access Interface , Change the default pvid by 2. So use the access mode .

E 0/0/4 For hybrid mode , All... Are not allowed vlan,pvid by 4

result

LSW2

E 0/0/1 Mixed interface mode , allow vlan 2 to 5 The label of

E 0/0/2 Interface mode , allow vlan 2 to 5 The label of

E 0/0/3 It is the access interface mode ,pvid by 2

E 0/0/4 Mixed interface mode ,pvid by 4, It is not allowed to bring vlan 1 to 4 The label of

result

LSW3

E 0/0/1 Mixed interface mode , allowed vlan2 to 5 All tags

E 0/0/3 Mixed interface mode ,pvid by 4, It is not allowed to bring vlan 2 to 4 label

E 0/0/4 Mixed interface mode ,pvid by 5, It is not allowed to bring vlan 2 to 3 5 label

result

result

PC1 Sure ping 2/4/5/6
