Question No. 5

Which three BGP messages pass EVPN information between devices? (Choose three.)

Show Answer Hide Answer
Correct Answer: A, B, E

A -- BGP open messages contain information used to negotiate the establishment of sessions but do not contain route information itself. They may contain information such as 'I can exchange EVPN AFI x/SAFI y NLRI with you', but not EVPN information itself.

B -- BGP update messages can contain EVPN NLRI information. This is the 'routing information' itself.

NOT C -- BGP notification messages indicate error conditions and contain basic error codes but no routing information. Technically they could refer to an error relating to EVPN, however this is not a good fit for the question being asked.

NOT D -- BGP keepalive messages are always 19 bytes and uniform; no NLRI information.

E -- A BGP speaker can send a ROUTE-REFRESH message to request the receiver re-sends their previously-sent BGP updates which, as per C, can include EVPN NLRI information.
