  1. IP Prefix Advertisement in EVPN draft-rabadan-l2vpn-evpn-prefix-advertisement-02 Jorge Rabadan WimHenderickx Florin Balus SenadPalislamovic Aldrin Isaac Ali Sajassi John Drake • IETF 90, July 2014 • Toronto, Canada

  2. Changes in version 02 • This draft defines EVPN route type 5 – IP Prefix route and describes how to use it through some use-cases • Two new co-authors added • Alignment with draft-sajassi-l2vpn-evpn-inter-subnet-forwarding • Complements the scenarios in the inter-subnet-forwarding draft with some use cases where the IP Prefix route is required • Use-case # 5 added • draft-draft-rabadan-l2vpn-evpn-prefix-advertisement-02 • IETF90 – July 2014

  3. Use-cases NEW Equivalent scenarios in draft-sajassi-l2vpn-evpn-inter-subnet-forwarding: (*) IRB forwarding on NVEs with core-facing IRB interface (**) IRB forwarding on NVEs without core-facing IRB interface • draft-draft-rabadan-l2vpn-evpn-prefix-advertisement-02 • IETF90 – July 2014

  4. Use-case #3: IP Prefix behind IRB IP ESI=0 • evpn RT=5 SN1 is imported into the IP-VRF with overlay NH = IRB3 IRB3 IP/MAC are installed in overlay ARP and FDB • evpn RT=2 VM NVE2 DGW-1 VNI=1 ESI=0 VNI=1 SN1 /24 IRB3 GW IP=IRB3 M2 / IRB3 IRB1 VXLAN/NVGRE WAN SN1 IRB4 IRB2 NVE3 DGW-2 EVI-10 EVI-10 EVI-10 EVI-2 EVI-2 EVI-10 VRF VRF VRF VRF • draft-draft-rabadan-l2vpn-evpn-prefix-advertisement-02 • IETF90 – July 2014

  5. Use-case #5: IRB forwarding without core-facing IRB NEW ESI=0 GW MAC=MAC-x SN1 is imported into the IP-VRF MAC-x used as inner MAC DA of packets to a host within SN1 • evpn RT=5 • BGP attribute NVE2 DGW-1 VNI=1 MAC-x SN1 /24 GW IP=0 VXLAN/NVGRE WAN SN1 MAC-y NVE3 DGW-2 EVI-2 EVI-2 VRF VRF VRF VRF • draft-draft-rabadan-l2vpn-evpn-prefix-advertisement-02 • IETF90 – July 2014

  6. Next steps • The authors would like to request WG adoption for this draft (along with draft-sajassi-l2vpn-evpn-inter-subnet-forwarding) • draft-draft-rabadan-l2vpn-evpn-prefix-advertisement-02 • IETF90 – July 2014
