EVPN pure type-5 route support

You can configure pure type-5 routing in an Ethernet VPN (EVPN) Virtual Extensible LAN (VXLAN) environment. Pure type-5 routing is used when the Layer 2 domain does not exist at the remote data centers. A pure type-5 route advertises the summary IP prefix and includes a BGP extended community called a router MAC, which is used to carry the MAC address of the sending switch and to provide next-hop reachability for the prefix. This router MAC extended community provides next-hop reachability without requiring an overlay next-hop or supporting type-2 route. To configure pure type-5 routing, include the ip-prefix-support advertise direct-nexthop statement at the [edit routing-instances routing-instance-name protocols evpn] hierarchy level.
