Layer 3 , Inter VLAN Routing

Lee_Mo
Level 1
Level 1

I have been try to set up inter VLAN as part of a university class using a Layer 3 switch and i am unsure what exactly is missing.


I have 3 Layer 2 switches with their own VLAN each.


MAN_PC_Block_1 - VLAN 10

MAN_PC_Block_2 - VLAN 20

MAN_PC_Block_3 - VLAN 30

 

I have been unsuccessful in having them ping across each other.

I have attached the config files if anyone can help. Thank you in advance

Hello there are some mismatches

 

  1. Switch MAN_Layer3 is giving access and trunk on ports 1,2 and 3 . These ports have to be either TRUNK only (if the MAN_PC_BLOCK_x SW performs client access), or only ACCESS (if the MAN_PC_BLOCK_x SW is acting as a hub) !
  2. Vlans 10.20 and 30 are not created in SW MAN_Layer3

  3. There is no vlan interface (SVI) of vlans 10.20 and 30 in SW MAN_Layer3 to perform routing between vlans.

    Change these itens and let us know if it will work.
Best regards

Hello,

 

where is the configuration of your Layer 3 switch ? Or the router (if you are using trunking and Router-on-a-stick) ?

 

I am using the layer 3 switch as routing , the router is solely for contacting outside the network. Layer 3 switch config attached.

In looking at the config of the layer 3 switch I do not see the config command 

ip routing

what kind of switch is this? Perhaps the output of 

show version
show ip protocol
show ip route

would be helpful.

The other issue is that I see access ports in vlans 10, 20, and 30. But I do not see vlan interfaces for these vlans. The vlan interface is a critical part of implementing inter vlan routing.
