Figure 93: Port Solver Protocol Messages Exchange to delete Second Remote Port<br />

Every time a PSMM is received, the correspondent entry of RP2 in the PST must be updated.<br />

Every time the LP is changed, the RP2 must be set to an invalid value <strong>and</strong> the protocol started.<br />

9.1.4.3.1 Port Solver Packet format<br />

The PSM is encapsulated using the CCP with Type0 0x02 <strong>and</strong> Type1 0x01 (Figure 94). The Port Solver packet will<br />

be sent through broadcast port 127.<br />
