Layer VPN Fig Overlapping VPNs In the figure below the Partner has connectivity to the Company HQ Site but not to other sites Overlapping VPNs can be implemented by using Route Targets in the correct manner The figure below depicts how the required connectivity can be achieved The implementation in the figure allows the Partner to reach all the networks at the Company HQ Site The actual requirement of the connectivity might be such that the Partner is allowed to access a certain server at the Company HQ Site, in which case only that prefix should be advertised to the Partner (RT=Partner) Fig Basic Overlapping VPN 8600 Smart Routers VPNs Configuration Guide 24 76.8600-50128F © 2014 Coriant Layer VPN 2.4.4 Management VPN The IP interconnectivity of management VPNs should be such that the management station can communicate with CE routers but the CE routers cannot communicate with each other The figure below shows the IP connectivity requirements It can be seen that from the IP connectivity point of view there are multiple overlapping VPNs The management station belongs to all those VPNs Fig Management VPNs The figure below shows one way of setting Route Targets in order to achieve the desired IP connectivity for management VPNs In the figure there are management VPNs and two intranets Note that it is enough that the management station learns one address that it can use for communication Other customer addresses must not be advertised towards 8000 intelligent network manager This is because of security reasons and in order to reduce addresses advertised to VRF to which the management station is connected RT=CE in the figure below should be attached only to one address (the loopback or interface address of CE) 76.8600-50128F © 2014 Coriant 8600 Smart

information on: • Default values to avoid unnecessary configuration • Available configuration options and parametric range To set up full mesh and hub-and-spoke layer VPNs, at least the following configuration tasks are required: • Configuration prerequisites: • Global IP routing; refer to the configuration examples in document 8600 IP Forwarding and Traffic Management Configuration Guide • MPLS switching; refer to the configuration examples in document 8600 MPLS Applications Configuration Guide • Layer 3VPN configuration: • 3.1 Full Mesh Layer VPN • 3.2 Hub-and-Spoke Layer VPN 3.1 Full

Private Network Configuration Examples 3.1.2 U-PE Customer Side Configuration (Full Mesh) Configuration tasks: • Static routing • OSPF routing • E-BGP routing • IP address and CE-VRF association for upe1, upe2 and upe3 • Associate the interface to the VRF • Configure the interface IP address Static Routing Static routes can be used between U-PE and CE This avoids the usage of any dynamic routing protocols In this configuration example router upe1 uses static routes Step Configure static routes towards the CE upe1(config)# ip route vrf vpnCust1 10.10.1.0/24 10.10.1.1 OSPF Routing The OSPF can be configured to exchange routes between U-PE and CE In this configuration example router upe2 uses the OSPF protocol Step Configure OSPF between the upe2 and customer CE upe2(config)# router ospf 10 vpnCust1 upe2(cfg-ospf[10])# redistribute bgp upe2(cfg-ospf[10])# network 10.10.2.0/24 area E-BGP Routing The BGP can be configured to exchange routes between U-PE and CE In this configuration example router upe3 uses the BGP protocol Step Configure eBGP between the upe3 and customer CE upe3(config)# router bgp 65003 upe3(cfg-bgp[65003])# address—family ipv4 vrf vpnCust1 upe3(cfg-bgp[65003]-af)# neighbor 10.10.3.1 IP Address and CE-VRF Association Configurations The customers need to be associated to the VRF before they can transmit or receive traffic This is done by associating interfaces to the VRF Step Associate the interface to the VRF 8660: upe1(config)# interface fe 5/1/1 8600 Smart Routers VPNs Configuration Guide 30 76.8600-50128F © 2014 Coriant Virtual Private Network

VRF 8660: upe2(config)# interface fe 5/1/2 upe2(cfg-if[fe 5/1/2])# ip vrf forwarding vpnCust1 Step Configure the interface IP address upe2(cfg-if[fe 5/1/2])# ip address 10.10.2.2/24 Step Associate the interface to the VRF 8660: upe3(config)# interface fe 5/1/3 upe3(cfg-if[fe 5/1/3])# ip vrf forwarding vpnCust1 Step Configure the interface IP address upe3(cfg-if[fe 5/1/3])# ip address 10.10.3.2/24 3.1.3 U-PE Network Side Configuration (Full Mesh) Since there is an RSVP-TE access network between upe3 and npe3, an RSVP-TE tunnel is needed between them It is assumed here that a separate tunnel is created for the VPN traffic Configuration tasks: • Create an RSVP-TE tunnel from upe3 to npe3 • MP-eBGP VPN configuration for upe1, upe2 and upe3 • Configure the neighbor router • Configure a loopback interface as a source of routing updates • Configure MP-eBGP for the VRF route exchange • Redistribute static routes to other VRFs RSVP-TE Tunnels to N-PEs Step Allow any VRF having affinity 0x01 to use this trunk The affinity is intended to be used if potential RSVP-TE tunnel users are wanted to be limited (in this example, for VRF) upe3(config)# rsvp-trunk upe3-npe3 upe3(cfg-rsvp-trunk[upe3-npe3])# map-route 0.0.0.0/0 mpls 0x01 Step Configure the tunnel destination upe3(cfg-rsvp-trunk[upe3-npe3])# to 171.19.13.13 MP-eBGP VPN Configuration upe1 configuration Step

full mesh; refer to chapter MP-eBGP VPN Configuration for instructions upe3 configuration For upe3, the following configurations are needed in addition to the full mesh configuration Step Allow re-advertisement of all routes containing a duplicate AS number (refers to Access Network AS number) upe3(config)# router bgp 65003 upe3(cfg-bgp[65003])# address-family ipv4 vrf vpnCust1ToSpokes

Distinguisher • Configure imported and exported routes towards the network VRF Configuration The difference between hub-and-spoke and full mesh is that different import and export Route Targets are needed since hub to spoke and spoke to hub traffic need to be separated npe1 configuration Step Create a VRF for traffic from Spokes npe1(config)# ip vrf vpnCust1FromSpokes Step Configure a Route Distinguisher npe1(cfg-vrf[vpnCust1FromSpokes])# rd 1:111 Step Configure the Route Target value for routes advertised by MP-BGP Route target = Spoke npe1(cfg-vrf[vpnCust1FromSpokes])# route-target

MP-BGP advertised routes Route target = Spoke npe1(cfg-vrf[vpnCust1FromSpokes])# route-target import 10:2 npe1(cfg-vrf[vpnCust1FromSpokes])# exit Step Create a VRF for traffic to Spokes npe1(config)# ip vrf vpnCust1ToSpokes Step Configure a Route Distinguisher npe1(cfg-vrf[vpnCust1ToSpokes])# rd 1:112 Step Configure the Route Target value for routes advertised by MP-BGP The exported Route Target is different in order to prevent unnecessary routes in other Spoke N-PEs (when more than one Spoke N-PEs) Route target = HubPE npe1(cfg-vrf[vpnCust1ToSpokes])# route-target export 10:12 Step Configure the Route Target value required for the accepted MP-BGP advertised routes Route target = Hub npe1(cfg-vrf[vpnCust1ToSpokes])# route-target import 10:1 npe3 configuration Step Create a VRF npe3(config)# ip vrf vpnCust1FromSpokes Step Configure a Route Distinguisher npe3(cfg-vrf[vpnCust1FromSpokes])# rd 1:131 Step Configure the Route Target value for routes advertised by MP-BGP Route target = Spoke npe3(cfg-vrf[vpnCust1FromSpokes])# route-target export 10:2 Step Configure the Route Target value required for the accepted MP-BGP advertised routes Route target = Spoke npe3(cfg-vrf[vpnCust1FromSpokes])# route-target import 10:2 npe3(cfg-vrf[vpnCust1FromSpokes])# exit Step Create a VRF npe3(config)# ip vrf vpnCust1ToSpokes Step Configure a Route Distinguisher npe3(cfg-vrf[vpnCust1ToSpokes])# rd 1:132 Step Configure the Route Target value for routes advertised by MP-BGP Route target = Hub npe3(cfg-vrf[vpnCust1ToSpokes])# route-target export 10:1 Step Configure the Route Target value required for the accepted MP-BGP advertised routes Route target = HubPE npe3(cfg-vrf[vpnCust1ToSpokes])# route-target import 10:12 3.3 Overlapping Layer VPN Basically overlapping VPNs are achieved only by importing several Route Targets 8600 Smart Routers VPNs Configuration Guide 38 76.8600-50128F © 2014 Coriant ...
