Somewhere, it is said that the behavior of network elements within a site doesn't change, which is thought to be one of the major strong feature of LISP. If that is the case, then the EID would be assigned to the interface like with the current Internet. > and the node moves around inside of the LISP site, it is up to existing > mechanisms to allow the mobility. > Assuming you really meant the node, not the interface, which existing mechanism would allow the mobility? OSPF or ISIS? If you meant, in fact, the interface but not the node in your discussion of the EID assignment, do you mean a MIP like mechanism would provide the mobility within a site? > So in the static case, that would mean a host route would need to be > injected into the IGP if the node's address stays the same I cannot catch what you exactly mean here by 'injection'.

Yes, no special mobility is provided by LISP itself... So, in short, what mobility solution is provided by LISP in addition to the existing mobility mechanisms? -- DY
