350-501 Architecture Practice Question
Which TWO statements about EVPN Route Type 2 (MAC/IP advertisement) are correct?
⚠ Common exam trap
Cisco often tests the distinction between EVPN Route Types, and the trap here is confusing the aliasing/load-balancing function of Route Type 1 with the MAC/IP advertisement function of Route Type 2, or assuming that the ESI is present in all EVPN routes.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It is used for MAC learning and ARP suppression
EVPN Route Type 2 is used to advertise MAC and IP addresses of hosts, enabling MAC learning and ARP suppression in EVPN-VXLAN fabrics. By distributing host MAC and IP bindings via BGP, it allows VTEPs to learn remote MAC addresses without data-plane flooding and to suppress ARP requests by responding locally when the IP-to-MAC mapping is known.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It is used for MAC learning and ARP suppression
Why this is correct
RT2 is used to populate MAC tables and suppress ARP.
- ✓
It advertises both MAC and IP addresses of hosts
Why this is correct
RT2 carries MAC and optionally IP address.
- ✗
It provides load balancing via aliasing
Why it's wrong here
Aliasing is done via Route Type 1.
- ✗
It includes the Ethernet Segment Identifier (ESI)
Why it's wrong here
ESI is part of Route Type 1 (Ethernet AD).
- ✗
It is not used for host mobility
Why it's wrong here
RT2 is used for host mobility tracking.
