Question

What are the two protocols redistributed into OMP? (Choose two.)

Options

AOSPF
BRIP
CLISP
DRSVP
EEIGRP

Explanation

OSPF and EIGRP are two common Interior Gateway Protocols (IGPs) that can be redistributed into OMP (Overlay Management Protocol) in a Cisco SD-WAN environment.

Common mistakes.

B. RIP (Routing Information Protocol) is an older and less commonly used IGP compared to OSPF and EIGRP in modern enterprise networks, and while technically possible to redistribute, OSPF and EIGRP are the two most prominent IGPs supported and discussed for redistribution into OMP.
C. LISP (Locator/ID Separation Protocol) is an overlay routing architecture and not an IGP typically redistributed into OMP; rather, it can coexist or be integrated differently.
D. RSVP (Resource Reservation Protocol) is a signaling protocol used for reserving resources in an IP network, primarily for QoS, not a routing protocol whose routes are redistributed into OMP.
