JN0-683 · Question #64
In your EVPN-VXAN environment, you want to prevent a multihomed server from receiving multiple copies of BUM traffic in active/active scenarios. Which EVPN route type would satisfy this requirement?
The correct answer is C. Type 4. In an EVPN-VXLAN environment with active-active multihoming, a multihomed server connected to multiple leaf switches can receive duplicate copies of BUM (Broadcast, Unknown Unicast, and Multicast) traffic. To prevent this, Type 4 (Ethernet Segment Route) is used. EVPN Type 4…

Explanation
In an EVPN-VXLAN environment with active-active multihoming, a multihomed server connected to multiple leaf switches can receive duplicate copies of BUM (Broadcast, Unknown Unicast, and Multicast) traffic. To prevent this, Type 4 (Ethernet Segment Route) is used. EVPN Type 4 routes are responsible for DF (Designated Forwarder) election, which ensures that only one leaf switch forwards BUM traffic to the multihomed server. This prevents duplicate frames and optimizes network efficiency.
