Zusammenfassung:	Disclosed is a technique to eliminate wasted tunneling encapsulation processing during redirection of a packet. According to the technique, when a packet of a first connection passing through a local mobility anchor ("LMA") 111 and a mobile access gateway ("MAG") 121 using a first prefix of an interface 131 of a mobile node ("MN") 130 is redirected to a second connection passing through a LMA 112 and a MAG 122 using a second prefix of an interface 132 of the MN 130, a redirection tunnel T1 is established between the LMA 111 and the LMA 112. When the MAG 122 knows the first prefix, the LMA 112 encapsulates a packet addressed to the first prefix that is redirected via the tunnel T to be addressed to the MAG 122 for transferring.
