The h<strong>os</strong>t sends out an IP packet that is intercepted by one of the xTRs <strong>and</strong> punted to the CPU,<br />

triggering a data plane–driven EID discovery event. The h<strong>os</strong>t IP traffic is the source IP<br />

address of the EID space defined for LISP. This EID is discovered <strong>and</strong> is added to the<br />

dynamic-eid table of the discovering xTR, as shown in Example 13-14.<br />
