Abstract
In general, techniques are described for providing control plane messaging in an active-active (or all-active) configuration of a multi-homed EVPN environment. In some examples, the techniques include receiving a control plane message comprising at least one address that identifies that second PE network device. The techniques may include configuring, based at least in part on the control plane message, a forwarding plane of a first PE network device to identify network packets having respective destination addresses that match the at least one address. The techniques may include determining that at least one address of the network packet matches the at least one address that identifies the second PE network device. The techniques may include, responsive to the determination, skipping a decrement of the Time-To-Live (TTL) value of the network packet, and forwarding the network packet to the second PE network device.
