1910-8G routing question

hi guys,

 

hope your well,

 

ive found this really good guide about intervlan routing

 

http://vmfocus.com/2012/09/26/how-to-configure-layer-3-static-routes-vlans-on-hp-v1910-24g/

 

this guide explains how to do intervlan routing on the switch and get the switch to route to the next hop ie the firewall/router, also i want to use it as a DHCP RELAY for the vlans on the switch,

 

on the link (below) do i just click on the radio button BOOTP or DHCP instead of selecting on MANUAL

Re: 1910-8G routing question

i mean the LAN port on my router /firewall has got the ip address 172.17.8.253 and then it goes to my vlan switch and the vlan it goes into is vlan 8 which is labelled as the server network i thought all i had to do was to create static routes in my router /firewall ie for all my networks ie

 

vlan 1 -(network) 172.17.1.0 (subnet) 255.255.255.0 (next hop) 172.17.1.254 OR (outbound interface) 172.17.8.253

 

vlan 2 - (network) 172.17.2.0 (subnet) 255.255.255.0 (next hop) 172.17.2.254 OR (outbound interface) 172.17.8.253

 

vlan 3 - (network) 172.17.3.0 (subnet) 255.255.255.0 (next hop) 172.17.3.254 OR (outbound interface) 172.17.8.253

 

vlan 8 - (network) 172.17.8.0 (subnet) 255.255.255.0 (next hop) 172.17.8.254 OR (outbound interface) 172.17.8.253

 

is this correct or not, sorry for the dumb question

Re: 1910-8G routing question

With your first question - that's the web management screen for your switch, right? If so, then you are configuring the IP address your switch will use to route for that VLAN/subnet, so I don't think you want to set it to obtain an IP address by DHCP...?

 

For your second question, your router needs routes for your internal subnets, as follows:

172.17.1.0 255.255.255.0 172.17.8.254

172.17.2.0 255.255.255.0 172.17.8.254

172.17.3.0 255.255.255.0 172.17.8.254

 
 The target for the route has to be an address in a subnet the router belongs to. It routes the packets to that address, from which they get routed by the switch.

 

You don't need a route for 172.17.8.0, because the router will already have a route for this subnet due to it being a subnet it already has an interface in that subnet.

 

When you say 172.17.8.0 is your "Server" subnet, does that mean you have hosts on it? If you are relying on your switch to route between VLANs, then you should use a different VLAN to connect to your router. You should not span a VLAN across two layer-3 devices.
