add_faucet_vip(vlan, faucet_vip)

add_host_fib_route_from_pkt(pkt_meta)

Add a host FIB route given packet from host.

Args:

pkt_meta (PacketMeta): received packet.

Returns:

list: OpenFlow messages.

add_route(vlan, ip_gw, ip_dst)

Add a route to the RIB.

Args:

vlan (vlan): VLAN containing this RIB. ip_gw (ipaddress.ip_address): IP address of nexthop. ip_dst (ipaddress.ip_network): destination IP network.

Returns:

list: OpenFlow messages.

advertise(vlan)

control_plane_handler(pkt_meta)

del_route(vlan, ip_dst)

Delete a route from the RIB.

Only one route with this exact destination is supported.

Args:

vlan (vlan): VLAN containing this RIB. ip_dst (ipaddress.ip_network): destination IP network.

Returns:

list: OpenFlow messages.

resolve_gateways(vlan, now)

Re/resolve all gateways.

Args:

vlan (vlan): VLAN containing this RIB/FIB. now (float): seconds since epoch.

Returns:

list: OpenFlow messages.
