Types

type Options

type Options struct {
	Logger *zerolog.Logger // if nil logging is disabled

	Passive bool // if true, expect the peer to go first with OPEN

	LocalASN      int        // local ASN; -1 means use remote (if Passive)
	LocalHoldTime int        // local hold time (s); -1 means use a default
	LocalId       netip.Addr // local identifier; unspecified means use remote-1 (if Passive)
	LocalCaps     caps.Caps  // additional local capabilities; set to nil to block a capability

	RemoteASN      int        // expected remote ASN; -1 means accept any
	RemoteHoldTime int        // minimum remote hold time (s); <= 0 means any
	RemoteId       netip.Addr // expected remote identifier; unspecified means any
	RemoteCaps     caps.Caps  // minimum remote capabilities; set to nil to block a capability
}

Options are BGP speaker options, see also DefaultOptions
