If I have VLAN 1 as 172.20.12.1/21 and VLAN 3 and 172.20.32.1/24 on a 5300xl...how can I get VLAN 1 to get to a server on VLAN 3? static route? Tagging? Any help would be so much appreciated. Thank you.
here's a snippet of my 5300 config...
ip routing
snmp-server community "public" Unrestricted
vlan 1
name "DEFAULT_VLAN"
untagged A1-A14,C8-C16,Trk3
ip address dhcp-bootp
tagged B2,Trk1
no untagged B1,B3-B14,C1-C7
exit
vlan 5
name "External_Net"
untagged B1-B14
ip address 192.168.1.2 255.255.255.0
tagged Trk1
exit
vlan 3
name "Voice_VLAN"
untagged C3-C7
ip address 172.20.32.1 255.255.255.0
tagged C1-C2,C15-C16,Trk1
exit
Solved! Go to Solution.

SolutionFrom your config, IP routing has been enabled in the CLI which is necessary for inter-VLAN routing.
All you need now are ip addresses assigned to the respective VLANs. When you assign an IP address to a VLAN you are in effect creating a virtual router.
Another thing to check in your config is that VLAN 1 (or any other VLAN that needs traffic routed) is not defined as the management VLAN as this will disable routing of non-management traffic into that VLAN.
Hope this helps, good luck!

Re: Totally simpleVLAN (rookie) question...sorry!
Anyway, I told you I was a rookie...you must've been shaking your head in disappointment.
Anyway, the reason for that was because our entire data network is on there. If I leave VLAN 1 as management, what addressing scheme should I use for that? Our network is simple as you can see. should it look more like this? and if so, that should be all I need. That, and not forcing dhcp on the routers.
VLAN 1 172.20.35.1/24 - our management
VLAN 2 172.20.8.1/21 --our data
VLAN 3 172.20.32.1/24 --our voice
VLAN 5 192.168.1.2/24 --our external net
Then, it's all about tagging the uplinks, right?

Re: Totally simpleVLAN (rookie) question...sorry!
Anyway my issue with not setting the address statically is that obviously on a switch reload the IP address may change, and this may or may not be an issue with access control lists (and other features) that rely on the VLAN ip address.
As far as addressing for management goes I don't see any issues with the scheme you have, though you may want to consider defining VLAN 1 as the management VLAN to prevent unwanted traffic from other VLANs from being routed there.
Yep just ensure your uplinks to other devices are tagged appropriately and I think you'll be fine.
On a side note probably want to change the default SNMP value from public especially since it is a unrestricted one.
Good luck!

Do not forget to set (default) routes on the communicating hosts pointing to the appropriate VLAN's addresses.
Good luck,
Dmitry

Re: Totally simpleVLAN (rookie) question...sorry!
do you mean for me to make sure that the computers have the proper gateway (the vlan interface IP)? If not, could you elaborate please?

Re: Totally simpleVLAN (rookie) question...sorry!
I believe I have done that. You know what...I was composing a reply with another question when I realized why my vlans weren't talking...wrong gateway on one of the machines...duh! Everything seems to be working exactly as I had hoped. Thank you all for your help. I can only hope to help someone else in the future on these forums. I wish I could dole out more points to you! Anyways, upwards and onwards I suppose. Take care.
