Exam 350-401 topic 1 question 623 discussion

- OMP routes: OMP Routes, also referred to as vRoutes, are prefixes learned at the local site via connected interfaces, static routes, and dynamic routing protocols (such as OSPF, EIGRP, and BGP) running on the service side of the vEdge. These prefixes are redistributed into OMP and advertised to the vSmart controller so that they can be carried across the overlay fabric to all other WAN edge nodes. OMP routes resolve their next-hop to a TLOC. An OMP route is installed in the forwarding table only if the next-hop TLOC is known and there is a BFD session in UP state associated with that TLOC; - TLOC routes advertise Transport Locators of the connected WAN transports, along with additional attributes such as public and private IP addresses, color, TLOC preference, site ID, weight, tags, and encryption keys. - Service routes advertise embedded network services such as firewalls and IPS that are connected to the vEdge local-site network.

Given answers are correct.

TLOC routes advertise TLOCs connected to the WAN transports, along with an extra set of attributes such as TLOC private and public IP addresses, carrier, preference, site ID, tag, weight, and encryption key information. Service routes represent services (firewall, IPS, application optimization, and so on) that are connected to the Cisco WAN Edge local-site network and are available for other sites for use with service insertion. In addition, these routes include originator System IP, TLOC, and VPN-IDs; the VPN labels are sent in this update type to tell the Cisco vSmart controllers which VPNs are serviced at a remote site.

OMP advertises three types of routes from Cisco WAN routers to Cisco vSmart controllers: OMP routes, or vRoutes, are prefixes that are learned from the local site, or service side, of a Cisco WAN Edge router. The prefixes are originated as static or connected routes, or from within the OSPF, BGP, or EIGRP protocol, and redistributed into OMP so they can be carried across the overlay. OMP routes advertise attributes such as transport location (TLOC) information, which is similar to a BGP next-hop IP address for the route, and other attributes such as origin, origin metric, originator, preference, site ID, tag, and VPN. An OMP route is only installed in the forwarding table if the TLOC to which it points is active.
