		int	intf
	)

Add host address to the routing table.

Parameters

unit	[IN] Unit number.
addr	[IN] 32 bit IP address value
intf	[IN] egress object created using example_create_l3_egress

Returns: OPENNSL_E_xxx OpenNSL API return code

		int	out_port,
		int	vlan,
		int	l3_eg_intf,
		opennsl_mac_t	next_hop_mac_addr,
		int *	intf
	)

create l3 egress object object includes next hop information.

  - packets sent to this interface will be send through out_port over
    given l3_eg_intf with next next_hop_mac_addr VLAN. SA is driven from
    l3_eg_intf as configure in example_create_l3_intf().

Parameters

unit	[IN] Unit number
flags	[IN] special controls set to zero
out_port	[IN] egress port
vlan	[IN] VLAN identifier
l3_eg_intf	[IN] egress router interface will derive (VLAN, SA)
next_hop_mac_addr	[IN] next hop mac address
*intf	[OUT] returned interface ID

Returns: OPENNSL_E_xxx OpenNSL API return code

		int *	l3_id
	)

Creates Router interface.

  - packets sent in from this interface identified by <port, vlan> with
    specificed MAC address is subject of routing
  - packets sent out through this interface will be encapsulated with
    <vlan, mac_addr>

Parameters

unit	[IN] Unit number.
open_vlan	[IN] if TRUE create given vlan, FALSE: vlan already opened juts use it
port	[IN] Port number
vid	[IN] router interface VLAN
mac_addr	[IN] my MAC address

Add default route to a subnet.

Parameters

subnet	[IN] 32 bit IP subnet
mask	[IN] 32 bit value network mask
intf	[IN] Egress object created using example_create_l3_egress
