Which information update is carried by OMP and enables the Cisco SD-WAN to build a secure overlay fabric on top of any public or private transport without regard for the actual link IP?
TLOC information is the OMP update that allows Cisco SD-WAN to build an overlay over any public or private transport without depending on the actual underlay link addressing. Cisco OMP advertises route reachability along with Transport Location mappings. A TLOC represents where and how a WAN Edge can be reached in the transport network, using attributes such as system IP, transport color, encapsulation, and next-hop information. Remote WAN Edge routers use this information to form secure data-plane tunnels to the correct transport attachment. RLOC is a LISP locator term associated with SD-Access and LISP designs, not the SD-WAN OMP construct. DTLS is the secure transport used for control connections, but it is not an OMP route information type. LISP PITR is unrelated to Cisco SD-WAN OMP. The secure overlay is built by combining OMP routes, TLOCs, policy, and encrypted tunnel establishment. Reference topics: Cisco SD-WAN OMP, TLOC routes, transport color, overlay routing, secure data-plane tunnels.
