WAN Edge Router Deployment
Question
Which two sets of identifiers OMP carry when it advertises TLOC routes between WAN Edge routers? (Choose two.)
Options
- ATLOC public and private address, carrier, and preference
- Bsource and destination IP address, MAC, and site ID
- Csystem IP address, link color, and encapsulation
- DVPN ID, local site, network, and BGP next-hop IP address
- ETLOC public and private address, tunnel ID, and performance
Explanation
OMP carries specific sets of identifiers in TLOC routes between WAN Edge routers, detailing tunnel endpoints and link characteristics.
Common mistakes.
- B. Source and destination IP addresses and MAC addresses are attributes of data plane packets, not routing updates for TLOCs, although site ID is used in OMP routes.
- D. VPN ID, local site, network, and BGP next-hop IP address are attributes primarily associated with OMP service routes (vRoutes), which describe prefixes reachable through a WAN Edge, rather than the TLOC routes themselves.
- E. While TLOC public and private addresses are correct, 'tunnel ID' is not a standard distinct OMP attribute in this context, and 'performance' is a dynamically derived metric rather than a static identifier carried directly within the TLOC route.
Concept tested. OMP TLOC route attributes
