3 VN 1: MLS TE LSs roblem Statement C0 1 BG/MLS I-VN E 1 E 2 2 VN VN 1?? C3 C4 5 : MLS TE LSs The 2 can t distinguish s between the VN1 and the VN2 when it sends them to the same destination. The 2 can t calculate an appropriate TE LS between s per a VN. The 1 can t distinguish CRep messages between the VN1 and the VN2 when it sends them to the same destination. The 1 can t reply the CRep messages corresponding to the s from CC/. 6 CRep message C7 3
