How can VLANs communicate?

[Dan-CRB]

Dears Cisco Community,

On cisco packet tracer need help how to VLANs can communicate ping or share or printing, I already have this basic configuration :

dan-crb>sh vlan brief

VLAN Name Status Ports

---- -------------------------------- --------- -------------------------------

1 default active Gig0/1, Gig0/2

10 VLAN0010 active

64 lantai1 active Fa0/1, Fa0/2, Fa0/3, Fa0/4

Fa0/5, Fa0/6, Fa0/7, Fa0/8

Fa0/9, Fa0/10, Fa0/11, Fa0/12

65 lantai2 active Fa0/13, Fa0/14, Fa0/15, Fa0/16

Fa0/17, Fa0/18, Fa0/19, Fa0/20

Fa0/21, Fa0/22

100 server-printer active Fa0/23, Fa0/24

1002 fddi-default active

1003 token-ring-default active

1004 fddinet-default active

1005 trnet-default active

Vlan64 10.174.64.3 YES manual up up

Vlan65 10.174.65.3 YES manual up up

Vlan100 192.168.100.3 YES manual up up

dan-crb> show ip route

Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP

i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area

* - candidate default, U - per-user static route, o - ODR

P - periodic downloaded static route

 

Gateway of last resort is not set

 

10.0.0.0/24 is subnetted, 2 subnets

C 10.174.64.0 is directly connected, Vlan64

C 10.174.65.0 is directly connected, Vlan65

C 192.168.100.0/24 is directly connected, Vlan100

Thank you in advance for your assistance!

As u see u have SVI interfaces Vlan 64,65,100 with IP addresses and UP UP state (show ip interfaces brief);  This puts those IPs as routes (networks) into routing table, aka RIB. -  see show ip routing - as C (connected routes).  L3 switches and routers can do routing on its own between directly connected networks (interfaces). In case of L3 switch, switch does routing between SVI interfaces (switched virtual interfaces).  you assign devices to particular vlan and subnet ( IP plus mask id) and connect them to access ports.  PCs belonging to vlan x can ping each others without any help inside that vlan x. PCs in vlan y need L3 device to reach PC in vlan x via SVI interfaces and switch RIB.  You can connect another PC directly to switch w/o Hub or L2 switch. Note: it is not recommended to use Hubs any longer in real world; good learning practice .though.   

Also, You can attach your PT file here but it must be in a zip format;
