The OpenBGPD package allows the BGP routing protocol to be used with pfSense® software.
Using in combination with CARP¶
The OpenBGPD package may be used in combination with CARP. It’s generally best to have two BGP sessions with each provider, one from each firewall, and set the nexthop in the BGP network statement to a CARP IP on the interconnect subnet with that upstream provider.
The latest version of the OpenBGP package includes a CARP status check IP address in the settings. Place a CARP VIP there and Save the settings. No additional patches or fixes are necessary.
