B
Ingress and egress PEs perform MAC and IP forwarding.
C
A routed-VXLAN interface is required on a per IP-VRF basis.
D
Each MAC-VRF used in the L3 EVPN network must exist on each PE.

Which of the following statements is FALSE?

A
The last octet of the default virtual MAC assigned to the sub-interface is derived from the last octet of the chassis MAC.
B
The same IP address used on this sub-interface can be used by other IRB sub-interfaces on remote PEs participating in the IP-VRF.
C
The host IP address of the sub-interface appears in the IP-VRF route table along with the prefix for the entire sub-net.
D
Two MAC addresses associated to the sub-interface are shown in the forwarding table of the MAC-VRF that contains the IRB sub-interface.

Correct Option:

QUESTION 3

Which of the following is always found in an extended community associated with an EVPN update?

A
The route target
B
The AFI/SAFI
C
The VXLAN network ID

A
RT-1 Ethernet Auto-Discovery
B
RT-2 MAC/IP Advertisement
C
RT-3 Inclusive Multicast Ethernet Tag
D

A
The route-distinguisher is a unique identifier that is configured per PE and per EVI.
B
It is included in each EVPN route update advertisement.
C
It is used by MP-BGP to allow for overlapping addresses from multiple tenants.
D
It identifies the EVPN instance in the control plane.

Correct Option:

QUESTION 6

Consider the exhibit.

All three leafs have an EVPN MP-BGP session with the route reflector in Spine-1. Leaf-2 and Leaf-3 have existing instances of an L2 EVPN named MAC VRF-1. Leaf-1 has just enabled a new instance of MAC VRF-1.

Which of the following steps is NOT taken when this new instance is enabled?

A
Leaf-1 generates an IMET route.
B
Leaf-1 advertises the IMET route in a BGP EVPN update directly to Leaf-2 and Leaf-3.
C
Leaf-2 and Leaf-3 auto-discover the new peer based on the route target in the received IMET route.
D
Leaf-2 and Leaf-3 add Leaf-1 to their existing flooding list for BUM traffic.

Correct Option:

QUESTION 7

e-BGP is used as the routing protocol in the data center underlay.

When configuring the EVPN MP-BGP route reflector sessions, which of the following statements is FALSE?

A
