Question
In Cisco SD-WAN, what protocol is used for control connections between SD-WAN devices?
Options
- ADTLS
- BOMP
- CBGP
- DOSPF
Explanation
In Cisco SD-WAN, the Overlay Management Protocol (OMP) is the routing protocol utilized for control connections between SD-WAN devices to exchange network topology and policy information.
Common mistakes.
- A. DTLS (Datagram Transport Layer Security) is the secure tunnel encapsulation protocol that secures the control connections, but OMP is the actual routing protocol that runs over these connections.
- C. BGP (Border Gateway Protocol) can be used for routing within the SD-WAN overlay in specific scenarios, but it is not the primary control connection protocol between core SD-WAN devices.
- D. OSPF (Open Shortest Path First) is an Interior Gateway Protocol (IGP) used in traditional LAN environments and may be used on the service side of a WAN Edge router, but not for control connections within the SD-WAN fabric.
