Example: Configuring Sender-Based RPF in a BGP MVPN with MLDP Point-to-Multipoint Provider Tunnels
This example shows how to configure sender-based reverse-path forwarding (RPF) in a BGP multicast VPN (MVPN). Sender-based RPF helps to prevent multiple provider edge (PE) routers from sending traffic into the core, thus preventing duplicate traffic being sent to a customer.
Requirements
No special configuration beyond device initialization is required before configuring this example.
Sender-based RPF is supported on MX Series platforms with MPC line cards. As a
prerequisite, the router must be set to network-services
enhanced-ip mode.
Sender-based RPF is supported only for MPLS BGP MVPNs with RSVP-TE point-to-multipoint provider tunnels. Both SPT-only and SPT-RPT MVPN modes are supported.
Sender-based RPF does not work when point-to-multipoint provider tunnels are used with label-switched interfaces (LSI). Junos OS only allocates a single LSI label for each VRF, and uses this label for all point-to-multipoint tunnels. Therefore, the label that the egress receives does not indicate the sending PE router. LSI labels currently cannot scale to create a unique label for each point-to-multipoint tunnel. As such, virtual tunnel interfaces (vt) must be used for sender-based RPF functionality with point-to-multipoint provider tunnels.
This example requires Junos OS Release 21.1R1 or later on the PE router that has sender-based RPF enabled.
Overview
This example shows a single autonomous system (intra-AS scenario) in which one source sends multicast traffic (group 224.1.1.1) into the VPN (VRF instance vpn-1). Two receivers subscribe to the group. They are connected to Device CE2 and Device CE3, respectively. MLDP point-to-multipoint LSPs with inclusive provider tunnels are set up among the PE routers. PIM (C-PIM) is configured on the PE-CE links.
For MPLS, the signaling control protocol used here is LDP. Optionally, you can use RSVP to signal both point-to-point and point-to-point tunnels.
OSPF is used for interior gateway protocol (IGP) connectivity, though IS-IS is also a supported option. If you use OSPF, you must enable OSPF traffic engineering.
For testing purposes, routers are used to simulate the source and the receivers.
Device PE2 and Device PE3 are configured to statically join the 224.1.1.1 group by
using the set protocols igmp interface interface-name
static group 224.1.1.1 command. In the case when a real multicast
receiver host is not available, as in this example, this static IGMP configuration
is useful. On the CE devices attached to the receivers, to make them listen to the
multicast group address, the example uses set protocols sap listen
224.1.1.1. A ping command is used to send multicast traffic into the
BGP MBPN.
Sender-based RPF is enabled on Device PE2, as follows:
[routing-instances vpn-1 protocols mvpn] user@PE2# set sender-based-rpf
You can optionally configure hot-root-standby with
sender-based-rpf.

Configuring Device PE2
Procedure
Step-by-Step Procedure
The following example requires that you navigate various levels in the configuration hierarchy. For information about navigating the CLI, see Using the CLI Editor in Configuration Mode in the Junos OS CLI User Guide.
To configure Device PE2:
-
Enable enhanced IP mode.
[edit chassis] user@PE2# set network-services enhanced-ip
-
Configure the device interfaces.
[edit interfaces] user@PE2# set ge-1/2/12 unit 0 family inet address 10.1.1.10/30 user@PE2# set ge-1/2/12 unit 0 family mpls user@PE2# set ge-1/2/14 unit 0 family inet address 10.1.1.17/30 user@PE2# set ge-1/2/14 unit 0 family mpls user@PE2# set vt-1/2/10 unit 4 family inet user@PE2# set lo0 unit 0 family inet address 10.1.1.4/32 user@PE2# set lo0 unit 104 family inet address 10.100.1.4/32
-
Configure IGMP on the interface facing the customer edge.
[edit protocols igmp] user@PE2# set interface ge-1/2/14.0
-
(Optional) Force the PE device to join the multicast group with a static configuration.
Normally, this would happen dynamically in a setup with real sources and receivers.
[edit protocols igmp] user@PE2# set interface ge-1/2/14.0 static group 224.1.1.1
-
Configure RSVP on the interfaces facing the provider core.
[edit protocols rsvp] user@PE2# set interface ge-1/2/0.10
-
Configure MPLS.
[edit protocols mpls] user@PE2# set traffic-engineering bgp-igp-both-ribs user@PE2# set label-switched-path p2mp-template template user@PE2# set label-switched-path p2mp-template p2mp user@PE2# set interface ge-1/2/12.0
-
Configure internal BGP (IBGP) among the PE routers.
[edit protocols bgp group ibgp] user@PE2# set type internal user@PE2# set local-address 10.1.1.4 user@PE2# set family inet unicast user@PE2# set family inet-vpn any user@PE2# set family inet-mvpn signaling user@PE2# set neighbor 10.1.1.2 user@PE2# set neighbor 10.1.1.5
-
Configure an OSPF or IS-IS.
[edit protocols ospf] user@PE2# set traffic-engineering user@PE2# set area 0.0.0.0 interface lo0.0 passive user@PE2# set area 0.0.0.0 interface ge-1/2/12.0
-
(Optional) Configure LDP.
RSVP can be used instead for MPLS signaling.
[edit protocols bgp group ibgp] user@PE2# set interface ge-1/2/12.0 user@PE2# set p2mp
-
Configure a routing policy to be used in the VPN.
The policy is used for exporting the BGP into the PE-CE IGP session.
[edit policy-options policy-statement parent_vpn_routes] user@PE2# set from protocol bgp user@PE2# set then accept
-
Configure the routing instance.
[edit routing-instances vpn-1] user@PE2# set instance-type vrf user@PE2# set interface vt-1/2/10.4 user@PE2# set interface ge-1/2/14.0 user@PE2# set interface lo0.104
-
Configure the provider tunnel.
[edit routing-instances vpn-1 provider-tunnel] user@PE2# set ldp-p2mp user@PE2# set selective group 225.0.1.0/24 source 0.0.0.0/0 ldp-p2mp user@PE2# set selective group 225.0.1.0/24 source 0.0.0.0/0 threshold-rate 0
-
Configure the VRF target.
In the context of unicast IPv4 routes, choosing
vrf-targethas two implications. First, every locally learned (in this case, direct and static) route at the VRF is exported to BGP with the specified route target (RT). Also, every received inet-vpn BGP route with that RT value is imported into the VRF vpn-1. This has the advantage of a simpler configuration, and the drawback of less flexibility in selecting and modifying the exported and imported routes. It also implies that the VPN is full mesh and all the PE routers get routes from each other, so complex configurations like hub-and-spoke or extranet are not feasible. If any of these features are required, it is necessary to usevrf-importandvrf-exportinstead.[edit ] user@PE2# set routing-instances vpn-1 vrf-target target:100:10
-
Configure the PE-CE OSPF session.
[edit routing-instances vpn-1 protocols ospf] user@PE2# set export parent_vpn_routes user@PE2# set area 0.0.0.0 interface lo0.104 passive user@PE2# set area 0.0.0.0 interface ge-1/2/14.0
-
Configure the PE-CE PIM session.
[edit routing-instances vpn-1 protocols pim] user@PE2# set rp static address 10.100.1.2 user@PE2# set interface ge-1/2/14.0 mode sparse
-
Enable the MVPN mode.
Both
rpt-sptandspt-onlyare supported with sender-based RPF.[edit routing-instances vpn-1 protocols mvpn] user@PE2# set mvpn-mode rpt-spt
-
Enable sender-based RPF.
[edit routing-instances vpn-1 protocols mvpn] user@PE2# set sender-based-rpf
-
Configure the router ID, the router distinguisher, and the AS number.
[edit routing-options] user@PE2# set router-id 10.1.1.4 user@PE2# set route-distinguisher-id 10.1.1.4 user@PE2# set autonomous-system 65001

Meaning
Both Device CE2 and Device CE3 send C-Join packets upstream to their neighboring PE routers, their unicast next-hop to reach the C-Source.
The C-Join state points to BGP as the upstream interface. Actually, there is no PIM neighbor relationship between the PEs. The downstream PE converts the C-PIM (C-S, C-G) state into a Type 7 source-tree join BGP route, and sends it to the upstream PE router toward the C-Source.
Checking the Multicast Routes
Purpose
Make sure that the C-Multicast flow is integrated in MVPN vpn-1 and sent by Device PE1 into the provider tunnel.

Meaning
The output shows that, unlike the other PE devices, Device PE2 is using sender-based RPF. The output on Device PE2 includes the upstream RPF sender. The Sender Id field is only shown when sender-based RPF is enabled.
