The displayed routes are EVPN routes shown in the formatNetwork(EthTagId/IpAddrLen/OriginalIp)with a /32 “OriginalIp” value (for example,0:32:1.1.1.0). In Huawei VXLAN BGP EVPN as described in HCIP Datacom Campus Network materials, this format corresponds toEVPN Route Type 3 (Inclusive Multicast Ethernet Tag Route). Type 3 routes are used by VTEPs to advertise participation information for a VXLAN broadcast domain (BD) and to provide the remote endpoint information needed for BUM (broadcast, unknown unicast, multicast) traffic handling.

Type 3 routes effectively carry theremote VTEP address information(the VTEP IP that serves as the tunnel destination in the underlay). Once the underlay Layer 3 network can reach that VTEP IP (for example, via IGP/BGP underlay routes), the VXLAN overlay can build forwarding toward the peer VTEP, so statementAis true and statementDis also true.

When ingress replication is used for BUM forwarding, the local VTEP needs a replication list of remote VTEPs in the BD. Receiving Type 3 routes provides the membership information required to form this list, making statementBtrue.

StatementCis false becauseType 2routes are MAC/IP Advertisement routes that include MAC information (and optionally a host /32 IP). The shown output contains no MAC fields, so it is not Type 2.
