Referring to the exhibit, which statement is correct when a failure exists on the link between host2 and switch5 on this EVPN-VXLAN fabric?
When a failure exists on the link between host2 and switch5, the EVPN-VXLAN fabric uses EVPN Type 1 routes, which are Ethernet Auto-Discovery (EAD) routes. Type 1 routes are used to advertise multi-homing Ethernet Segment Identifier (ESI) as part of the auto-discovery process and to facilitate rapid convergence in case of a link or node failure. Upon detecting the link failure, switch5 would withdraw the Ethernet Auto-Discovery routes, signaling to all peers that the connection to host2 via switch5 is no longer available. This ensures other switches can quickly reroute traffic accordingly.
Type 1 routes are used for per-ES auto-discovery (A-D) to advertise EVPN multi-homing mode. Remote ToR leaf devices in the EVPN network use the EVPN Type 1 route type functionality to learn the EVPN Type 2 MAC routes from other leaf devices. In this route type ESI and the Ethernet Tag ID are considered to be part of the prefix in the NLRI. Upon a link failure between ToR leaf and end server VTEP withdraws Ethernet Auto-Discovery routes (Type 1) per ES. The Juniper EVPN multi-homing Ethernet Tag value is set to the VLAN ID for ES auto-discovery/ES route types. Mass Withdrawal - Used for fast convergence during link failure scenarios between leaf devices to the end server using Type 1 EAD/ES routes.
