See a similar scenario with the Quagga router.


1. CASE PRINCIPLE

Vyatta version used: VC 2.0 Feb 20, 2007
In this second case study, we will see an example where two Desktops are connected between each other through two routers, one Cisco 2651 router and one Vyatta router.
The routers use the OSPF dynamic routing protocol to advertise the IP networks.


Read the Vyatta policy about the Community Edition.
