Question

Which attribute identifies the type of a vRoute?

Options

Aoriginator
Btag
Corigin
Dencapsulation

Explanation

The 'origin' attribute in Cisco SD-WAN identifies the type of a vRoute, indicating how the route was learned (e.g., OSPF, BGP, connected, static).

Common mistakes.

A. The 'originator' attribute identifies the system IP address of the WAN Edge router that originated the route, not its type.
B. The 'tag' attribute is an optional, user-defined value that can be added to routes for policy matching, not to specify the route type.
D. 'Encapsulation' refers to the tunnel type (e.g., IPsec, GRE) used for data plane traffic, not an attribute that identifies the route type itself.
