VLAN routing between subnets

Hi

 

I have a client who was a current office network of 192.168.10.0/24 and this routes through to a private network 10.1.10.0/24 in a datacentre with hosted servers.

Default gateways are 192.168.10.254 and 10.1.10.254.

Both networks can currently talk to each other.

 

 

I need to bring the private network into the office and allow both networks to communicate with each other.

The private network will be turned off and the servers from there will be brought into the office on the 192.168.10.0/24 network.

 

I am setting up a switch to allow this and the other company is configuring the routers.

 

Below is my switch configuration.

 

hostname "Aruba-2930F-48G-4SFP"
module 1 type jl260a
ip default-gateway 192.168.10.254
ip route 0.0.0.0 0.0.0.0 192.168.10.254
snmp-server community "public" unrestricted
vlan 1
name "DEFAULT_VLAN"
no untagged 32-40
untagged 1-31,41-52
ip address 192.168.10.150 255.255.255.0
exit
vlan 10
name "10.1.10.x"
untagged 32-40
tagged 48
ip address 10.1.10.254 255.255.255.0
exit
no tftp server
no autorun
no dhcp config-file-update
no dhcp image-file-update
password manager
password operator

 

I have a vmware machine which will be using vlan id 10.

Just wanted to find out if this configuration would work ok.

 

Thanks

Jimi

Re: VLAN routing between subnets

Couple of things I've noticed.

 

You don't have ip routing enabled.

 

With IP routing enabled, you don't need following command:

ip default-gateway 192.168.10.254

VLAN 1 is untagged for port 48 and VLAN 10 is untagged for the same VLAN? Just wanted to maek sure this is what you want. Trunk ports should be tagged for desired VLAN and access portd should be untagged for specific VLANs

 

For house keeping, change the default SNMP string.

Re: VLAN routing between subnets

Thanks for the reply.

I have now updated the switch config to

 

; JL260A Configuration Editor; Created on release #WC.16.08.0001
; Ver #14:07.6f.f8.1d.9b.3f.bf.bb.ef.7c.59.fc.6b.fb.9f.fc.ff.ff.37.ef:24
hostname "Aruba-2930F-48G-4SFP"
module 1 type jl260a
ip default-gateway 192.168.10.254
ip route 0.0.0.0 0.0.0.0 192.168.10.254
ip routing
snmp-server community "....." operator unrestricted
vlan 1
name "DEFAULT_VLAN"
no untagged 32-40
untagged 1-31,41-52
ip address 192.168.10.210 255.255.255.0
exit
vlan 10
name "10.1.10.x"
untagged 32-40
tagged 48
ip address 10.1.10.254 255.255.255.0
exit
no tftp server
no autorun
no dhcp config-file-update
no dhcp image-file-update
password manager
password operator

 

The other  company is going to route the 10.1.10.x network through to the 10.1.10.254 gateway on the switch and their router , currently on 192.168.10.254 will be routed through to 192.168.10.210 on the switch.

 

This switch will be plugged into the current switch on the 192.168.10.x subnet. This does not have any other VLAN setup

 

Does this sound correct as in the two subnets should talk to each other through the router. Which would mean I can set a port to Vlan 10 untagged or the default VLAN untagged and they should communicate across all switches.

 

thanks

Jimi
