Method Detail

bindToUdp

@Bind(to=Udp.class)
public static boolean bindToUdp(JPacket packet,
                                                Udp udp)

Bind to UDP port 520 which is the default for RIP.

Parameters:

packet - current packet

udp - udp header within this packet

Returns:

true if binding succeeded or false if failed

headerLength

@HeaderLength
public static int headerLength(JBuffer buffer,
                                            int offset)

Header length.

Parameters:

buffer - the buffer

offset - the offset

Returns:

the int

command

@Field(offset=0,
       length=8)
public int command()

Command.

Returns:

the int

commandDescription

@Dynamic(value=DESCRIPTION)
public java.lang.String commandDescription()

Command description.

Returns:

the string

commandEnum

public Rip.Command commandEnum()

Command enum.

Returns:

the command

count

public int count()

Gets the number of entries in the routing table.

Returns:

count of number of 20 byte entries in the routing table

decodeHeader

protected void decodeHeader()

The routing table is the only thing that needs decoding. The routing table is lazy decoded.

Overrides:

decodeHeader in class JHeader

version

@Field(offset=8,
       length=8)
public int version()

Version.

Returns:

the int
