BGP EVPN defines several types of BGP EVPN routes by extending BGP. Type ? routes are used to advertise host IP routes and external network routes. (Enter only digits.)
正確答案:
5
Explanation:
BGP EVPN (Ethernet VPN) extends BGP to provide control plane functionality for VXLAN overlays, including in Huawei's data center networks. EVPN defines several route types to advertise different types of information:
Type 1: Auto-discovery routes for EVPN instances.
Type 2: MAC/IP Advertisement routes for host reachability.
Type 3: Inclusive Multicast Ethernet Tag routes for multicast traffic.
Type 4: Ethernet Segment routes for multi-homing.
Type 5: IP Prefix routes for advertising host IP routes and external network routes, enabling inter- subnet and external connectivity.
The question specifies routes used to advertise "host IP routes and external network routes," which aligns with Type 5 routes. These routes carry IP prefix information and a Layer 3 VNI, facilitating Layer 3 routing within the EVPN domain or to external networks. Thus, the answer is 5.
