Chapter 2 Advanced Routing for FortiOS 5.0 : Border Gateway Protocol (BGP) : Dual-homed BGP example : Network layout and assumptions : Assumptions
  
Assumptions
The basic BGP configuration procedure follows these assumptions:
ISP1 is the preferred route, and ISP2 is the secondary route
all basic configuration can be completed in both GUI and CLI
only one AS is used for the Company
For these reasons this example configuration does not include:
Bi-directional forwarding detection (BFD)
Route maps
Access lists
changing redistribution defaults — make link when example is set up
IPv6
For more information on these features, see the corresponding section.
