Configure OSPF with Extreme EXOS - Area Zero

Here is the outline for how to get OSPF running on 3 Extreme routers and then connecting them to a Cisco router to simulate an outside connection.

Here is a video if you want to watch:  https://www.youtube.com/watch?v=YZkAzKoZlz4

Things to keep in mind

• Your Router that will be connecting your the WAN/Internet needs to have "OSPF export"  to route the other interfaces in your ospf domain.  I am doing this with a static route in "Extreme 1"
• If you have interfaces on a local router you will advertise them by exporting them as "direct" routes.
• All routers need to be in the same area.  Area 0.0.0.0 is the default.
• Every router needs to have a different RouterID.
• Vlan 999 is my link out to the WAN.

Configure Vlan Extreme Networks EXOS - Basic VLAN Config Guide

This is a basic guide to get a Extreme Networks EXOS router up and going.  I am working with a Extreme X670-G2 and it is running on Code Version 21.

Create Vlan:

create vlan 900
      *  If you use numbers when you create your vlan it will show up as "VLAN_900"
      *  If you are using just text your vlan will just be in quotation marks.  ex:  "employees"

configure vlan "VLAN_0900" tag 900
    * This sets the numerical value of your vlan to your created vlan.
    * This DOES NOT tag you vlan.

configure vlan VLAN_0900 add ports 48 tagged (or untagged)
   *  This command will allow you to tag or untag your vlan on a port.

configure vlan VLAN_0900 ipaddress 10.255.251.1/30
   *  Configure a routed interface.

enable ipforwarding vlan VLAN_0900
   *  allows your interface to forward traffic through the vlan to the next hop.

Quick Setup:

create vlan 900
configure vlan "VLAN_0900" tag 900
configure vlan VLAN_0900 add ports 48 tagged (or untagged)
configure vlan VLAN_0900 ipaddress 10.255.251.1/30
enable ipforwarding vlan VLAN_0900

Extreme Network How to Guides

I am new to Extreme Network,  I came from a Enterasys and Cisco background so I am slowly converting to Extreme Network's XOS operating system.

There command structure, in my opinion is more "human" than cisco which I like but there are still some funky commands.  So this blog will hopefully help you along with starting out.
