This field has no * relation to the "Lifetime" field within the ICMP Router * Advertisement portion of the Agent Advertisement. * * R Registration required. Registration with this foreign * agent (or another foreign agent on this link) is required * rather than using a co-located care-of address. * * B Busy. The foreign agent will not accept registrations * from additional mobile nodes. * * H Home agent. This agent offers service as a home agent * on the link on which this Agent Advertisement message is * sent. * * F Foreign agent. This agent offers service as a foreign * agent on the link on which this Agent Advertisement * message is sent. * * M Minimal encapsulation. This agent implements receiving * tunneled datagrams that use minimal encapsulation [15]. * * G GRE encapsulation. This agent implements receiving * tunneled datagrams that use GRE encapsulation [8]. * * V Van Jacobson header compression. This agent supports use * of Van Jacobson header compression [10] over the link * with any registered mobile node. * * reserved sent as zero; ignored on reception. * * Care-of Address(es) * The advertised foreign agent care-of address(es) provided * by this foreign agent. An Agent Advertisement MUST * include at least one care-of address if the 'F' bit * is set. The number of care-of addresses present is * determined by the Length field in the Extension. * * A HA must always be prepared to serve the mobile nodes for * which it is the home agent. A FA may at times be too busy * to serve additional MNs; even so, it must continue to send * Agent Advertisements, so that any mobile nodes already registered * with it will know that they have not moved out of range of the * foreign agent and that the has not failed. A foreign * agent may indicate that it is "too busy" to allow new MNs to * register with it, by setting the 'B' bit in its Agent Adv. * An Agent Adv message MUST NOT have the 'B' bit set if the * 'F' bit is not also set, and at least one of the 'F' bit and the * 'H' bit MUST be set in any Agent Advertisement message sent. * * When a FA wishes to require registration even from those * mobile nodes which have acquired a co-located care-of address, it * sets the 'R' bit to one. Because this bit applies only to foreign * agents, an agent MUST NOT set the 'R' bit to one unless the 'F' * bit is also set to one. */ #ifdef __sparc #ifdef _BIT_FIELDS_HTOL typedef struct mobility_agt_adv_extension { uchar_t type; uchar_t length; ushort_t sequence_num; ushort_t reg_lifetime; ushort_t reg_bit:1, busy_bit:1, ha_bit:1, fa_bit:1, minencap_bit:1, greencap_bit:1, vanjacob_hdr_comp_bit:1, reverse_tunnel_bit:1, reserved:8; } mobagtadvext_t; #endif /* _BIT_FIELDS_HTOL */ #endif /* __sparc */ #ifdef __i386 #ifdef _BIT_FIELDS_LTOH typedef struct mobility_agt_adv_extension { uchar_t type; uchar_t length; ushort_t sequence_num; ushort_t reg_lifetime; uchar_t reverse_tunnel_bit:1, vanjacob_hdr_comp_bit:1, greencap_bit:1, minencap_bit:1, fa_bit:1, ha_bit:1, busy_bit:1, reg_bit:1; uchar_t reserved; } mobagtadvext_t; #endif /* _BIT_FIELDS_LTOH */ #endif /* __i386 */ #ifdef __cplusplus } #endif #endif /* _SNOOP_MIP_H */
