SDN Migration Tutorial Part 1

In late August, we will be presenting a tutorial at the OpenDaylight Summit.  As we get ready, we are preparing the configurations for the devices involved in the tutorial.  At this time, the tutorial includes a pair of Pica8 Switches and a pair of Cisco ISR routers.  For diversity, we may swap out some of the devices for other vendors.


The initial setup involves the Pica8 switches (L3Sw 1/L3SW 4) in standard L2/L3 mode running OSPF and BGP.

The configuration for L3SW1 with host 1 attached is straight forward (for those who are familiar with how to configure PicOS).

The interfaces are configured in their own VLANs (101, 102) with the uplinks configured as trunks and including the VLAN facing the host (10).

For the VLANs we have added a specific IP to the loopback interface and the link IPs for each of the normal interfaces.

The routing protocols are setup so that the loopback address is advertised into OSPF and the BGP peering is done between the loopback addresses of the switches.

The policy in use by BGP advertises the connected route (Host 1).

The configuration of the second switch (L3SW 4) is very similar, with only the interface IPs and networks being advertised being different.

This concludes part 1 of the SDN tutorial configuration.

    Hi Steve,
    Good tutorial on SDN testing. I saw another article on comparing SDN controller (ONOS and ODL). We are a wireless service provider trying to make a decision on Controller. I would like to get your suggestion as which Controller we should go with.
