Juniper JN0-664 Exam - Topic 2 Question 67 Discussion

Posted by Virgie on Jul 17, 2026 at 12:32 PM

Which two EVPN route types are used to advertise a multihomed Ethernet segment? (Choose two )

Suggested Answer: A, C

EVPN is a solution that provides Ethernet multipoint services over MPLS networks. EVPN uses BGP to distribute endpoint provisioning information and set up pseudowires between PE devices. EVPN uses different route types to convey different information in the control plane. The following are the main EVPN route types:

Type 1 - Ethernet Auto-Discovery Route: This route type is used for network-wide messaging and discovery of other PE devices that are part of the same EVPN instance. It also carries information about the redundancy mode and load balancing algorithm of the PE devices.

Type 2 - MAC/IP Advertisement Route: This route type is used for MAC and IP address learning and advertisement between PE devices. It also carries information about the Ethernet segment identifier (ESI) and the label for forwarding traffic to the MAC or IP address.

Type 3 - Inclusive Multicast Ethernet Tag Route: This route type is used for broadcast, unknown unicast, and multicast (BUM) traffic forwarding. It also carries information about the multicast group and the label for forwarding BUM traffic.

Type 4 - Ethernet Segment Route: This route type is used for multihoming scenarios, where a CE device is connected to more than one PE device. It also carries information about the ESI and the designated forwarder (DF) election process.

I’m pretty confident that Type 2 is used for advertising multihomed segments, but I’m torn between Type 3 and Type 4 for the second option.

I feel like Type 4 was mentioned in relation to multihoming, but I might be mixing it up with another topic.

I remember practicing a question like this, and I think Type 1 is definitely one of them, but I can't recall the second one.

I think Type 2 and Type 3 are the ones we discussed in class for multihomed segments, but I'm not completely sure.
