1  Reference:  Vehicle has 2 MANET routers, interconnected via Ethernet  Vehicle has access to 3 wireless networks  Applications on MANET Routers use “loopback interface”  Attached nodes typically are hosts, may be routers (N: node) Vehicle networks MNR NNN

2  Interfaces are assigned a sub-prefix from the delegated prefix  Example: /25 for Ethernet, /32 for “loopback interfaces”  CIDR “longest match” forwarding algorithm Prefix delegation (IPv4) MNR p = /25 NNN p.1 p.2 p.11p.12p / /32 MNR Delegated prefix = /24

3  Follows same model as IPv4  Use ULA instead of RFC1918 private addresses Prefix delegation (IPv6) MNR P = FD:1:2:120::/64 NNN p::1p::2 p::Bp::Cp::D FD:1:2:12F::1/128 FD:1:2:12F::2/128 Delegated prefix = FD:1:2:120::/60 MNR

4  IPv6 routing protocols typically use link-local addresses  Likely unique EUI-64 layer-2 address  Cryptographically Generated Addresses (RFC3972)  Randomized Interface Identifiers (RFC4941) IPv6 link-local addresses FE80::InterfaceID/64 NNN FD:1:2:120::/60 MNR

5  RFC /16 prefix;  Or allocate new address block (e.g. out of class E) ??  Static or automatic configuration  What InterfaceID is used ? IPv4 link-local addresses NNN MNR x.y/ /24

6 A simple MANET Router  MANET protocol uses link-local  On a MANET router with a single MANET interface, a unique address may be configured on it MNR unique address or link-local
