 This configuration sets up a simple BGP test environment with two nodes.
 
 Node a runs FRRouting (FRR) as a BGP speaker with IPv4 and IPv6 addresses on interface
-eth1, while node b runs the BIRD routing daemon configured similarly. Both nodes establish
+eth1, while node b runs the BIRD and node c the GoBGP routing daemon configured similarly. All nodes establish
 BGP peering over IPv4 and IPv6 with each other.
