Cannot re-use peer address

[wez470]

Doing an action like below will cause an err

peer1 := &api.Peer{
	Conf: &api.PeerConf{
		NeighborAddress: "127.0.0.1",
		PeerAsn:         11111,
	},
	Transport: &api.Transport{
		RemotePort: 10179,
	},
	Timers: &api.Timers{
		Config: &api.TimersConfig{
			ConnectRetry:           1,
			IdleHoldTimeAfterReset: 1,
		},
	},
}
myBGPServer.AddPeer(context.Background(), &api.AddPeerRequest{Peer: peer1})
peer2 := &api.Peer{
	Conf: &api.PeerConf{
		NeighborAddress: "127.0.0.1",
		PeerAsn:         22222,
	},
	Transport: &api.Transport{
		RemotePort: 20179,
	},
	Timers: &api.Timers{
		Config: &api.TimersConfig{
			ConnectRetry:           1,
			IdleHoldTimeAfterReset: 1,
		},
	},
}
err := myBGPServer.AddPeer(context.Background(), &api.AddPeerRequest{Peer: peer2})
fmt.Println(err)

can't overwrite the existing peer: 127.0.0.1

Because the neighbour map uses address string only as the key. You can bypass this one time on local by changing one of the peers to "localhost". It would be useful (mostly for testing) if the PeerAsn was used as part of the neighbour map key so multiple peers can live at a single address.

You can use 127.0.0.1 and 127.0.0.2.
