This object specifies the attributes of the mobility tunnel. none(0) - The mobility network-id is not supported on L3MM. trusted(1) - By default, a mobility network is considered 'untrusted'. In an untrusted network, Mobile Nodes are required to use a DHCP-obtained IP address. In a 'trusted' network, Mobile Nodes are allowed to use static IP addresses. On an untrusted network, data forwarding path for a Mobile Node is established and updated by snooping DHCP packets between the Mobile Node and the DHCP server. On the other hand, a trusted network data path establishment and update is achieved by snooping IP packets generated by the Mobile Node. broadcast(2) - IP broadcast is allowed on the mobility network-id corresponding to this tunnel. tcpMssAdjust(3)- The Access Point should do a TCP Maximum Segment Size (MSS) adjustment for the tunnel corresponding to the mobility network-id. dynamic(4) - Wireless broadcast domain corresponding to mobility network-id is dynamically created on an Access Point. multicast(5) - IP multicast is allowed on the mobility network-id corresponding to this tunnel. ipDiscovery(6) - IP broadcast pings will be generated to discover the IP address of the wireless client.
