Routed port to layer 2 access switch config

gelspot777
Level 1
Level 1

Hi All

I would like to know if this scenario works if not please let me know what need to be corrected.

Design as shown in attached diagram.

Distribution switch -connected to 3560---and conected to 2950 access switch .

A van 777 is created in distribution switch and that VLan is exteded to 2nd switch 3560

Distribution has route pointing to 3560 to reach the subnet 10.0.0.0/24

No I will make one of the interface Gi/25 in 3560 as routed port with an ip 10.0.0.1/24.

I connect Gi/25 to the access switch 2950  fa 0/24.

3560 has routing pointing back to Distribution

2950 config as below

Has default vlan 1 with an ip 10.0.0.34/24.

Users behind 2950 has gateway of 10.0.0.1/24

fa 0/24 is set with default config (do i need to place this interface in Vlan 777 / or do i need delete vlan 1 and create vlan 777 in 2950)

Please help, thanks in advance

w r t your statement

"If you are just connecting the 2950 to the  3560 on vlan 777  or a routed port from the 3560  , if you are not trunking other vlans down to the 2950 the vlan on the 2950 can be anything  you want or just leave it in vlan 1 .  From a troubleshooting perspective and  knowledge point of view its probably best you make the  2950 vlan 777 with alll ports in vlan 777 though this is "not" required to make it work ."

Hi Glen ,

Before I go and implement let me understand this correctly . not sure if you are aware that 3560 and 2950 are in different subnet .


With reference to my attached diagram , let me explain my aim once again

interface vlan 777 is configured on 4500 distribution

VLan 777 is created in layer 2 switch 3600 which is in subnet 10.1.0.0/24

Now there is another user access switch 2950 which is in vlan 10.0.0.0/24 subnet

Now if I connect this 10.0.0.0/24 network to 3600 and makig the connected interface as  routed interface .

So if I make the config in this way , want to know can 10.0.0.0/24 talk to 10.1.0.0/24 network . if not please let me know how the config should be

Thanks in advance
