Scenario: An ISP wants to offer MPLS L3 VPN Hub and Spoke Services to its customer along with the the need to provide the HUB servcies in alternate redundant way such that HUB1 will be primary for spoke-A, secondary for spoke-B HUB2 will be primary for spoke-B, secondary for spoke-A
Design Consideration and Solution:
1. HUB & Spoke Services
We will require 2 VRFs on the HUB-PEs viz one Hub_Ingress VRF to collect the routes from the remote spoke PE and send it towards the HUB and one Hub_Egress VRF to send the Hub_Routes as well as remote Spoke Routes from the HUB back to the MP-iBGP cloud. Having said that we would need two logical L3 peering between HUB PE-CE . One peering to be part of Hub_Ingress VRF and other Peering to be part of Hub_Egress VRF..We will have two eBGP neighbourship between HUB PE-CE ie one per VRF..
Also an important point to consider here is that because of default AS-Path Loop Prevention mechanism of BGP on the HUB-PEs under HUB_Egress VRF BGP Neighbourship config we need to add " allowas-in " command so that the spokes routes sent via HUB_Ingress VRF are not dropped when coming back to the HUB PE.
2. Alternate Redundant HUB Services to Spokes
To achive the deisgn such that Spoke 1 is services by HUB1 as Primary and HUB2 as Secondary and vice-versa for Spoke 2 we would need to design the RTs in such a way that on the remote spoke PE we can macth on the unique RT value and change the local preference of the HUB_PE2 routes under Spoke1_VRF to Lower Value so that Spoke1 prefers HUB1 PE as Primary and similarly we need to macth on the unique RT value and change the local preference of the HUB_PE2 routes under Spoke2_VRF to Lower Value so that Spoke1 prefers HUB1 PE as Primary
So from the above points the VRF Design would be as below
HUB-PE1
VRF: HUB1_Ingress
rd 64513:1
route-target import 64513:200
route-target import 64513:300
VRF: HUB1_Egress
rd 64513:2
route-target export 64513:100
HUB-PE2
VRF: HUB2_Ingress
rd 64513:3
route-target import 64513:200
route-target import 64513:300
VRF: HUB1_Egress
rd 64513:4
route-target export 64513:400
Spoke-PE
VRF: Spoke1
rd 64513:5
route-target import 64513:100
route-target import 64513:400
route-target export 64513:200
VRF: Spoke2
rd 64513:6
route-target import 64513:100
route-target import 64513:400
route-target export 64513:300
Also on Spoke PE we need to apply inbound import-map to change the LP to higher value as discussed above
SPoke PE
ip vrf Spoke1
import map HUB1
!
ip vrf Spoke2
import map HUB2
!
route-map HUB1 permit 10
match extcommunity HUB2
set local-preference 50
!
route-map HUB1 permit 20
!
route-map HUB2 permit 10
match extcommunity HUB1
set local-preference 50
!
route-map HUB2 permit 20
!
ip extcommunity-list standard HUB1 permit rt 64513:100
ip extcommunity-list standard HUB2 permit rt 64513:400
Also to ensure that HUB_CE to Spoke1 Traffic flows via HUB1-PE1 and HUB_CE to Spoke2
Traffic flows via HUB2-PE2 we use standard BGP community tagging at PE1 for Spoke2 routes and at PE2 for Spoke1 routes such that on HUB1 while redistributing BGP to OSPF we set the metric for Spoke2 routes to higher value and same ways on HUB2 while redistributing BGP to OSPF we set the metric for Spoke1 routes to higher value
ISP IGP used ISIS Level-2
Hub PE-CE ROuting Protocol used eBGP
Spoke PE-CE ROuting Protocol used OSPF Area 0
ISP AS used 64513
HUB1 AS used 64514
HUB2 AS used 64515
HUB_CE IGP used OSPF Area 0
Standard Community for Spoke1 64513:2000
Standard Community for Spoke2 64513:3000
