Inter-VRF Multicast without unicast Inter-VRF route leaking

Image
INTRODUCTION ON ASR1000, an IOS-XE device we will forward multicast stream coming from a source in VRF 'source' and going towards users in VRF 'receiver' without doing unicast inter-VRF route leaking  TOPOLOGY CONFIGURATION Generating UDP multicast stream on the source.  Source# ip sla 1  udp-echo 239.1.1.1 2000 source-ip 10.1.1.1 ip sla schedule 1 life forever start-time now Receiver is configured with IGMP and sending IGMP membership report.  ASR1000 router is doing the inter-vrf multicast traffic forwarding. Loopback 1 in VRF 'source' is the RP for both the VRFs.  ASR1000# ip vrf source  rd 1:1 ! ip vrf receiver  rd 2:2 ! ip multicast-routing vrf source distributed ip multicast-routing vrf receiver distributed ip pim vrf source rp-address 1.1.1.1 ip pim vrf receiver rp-address 1.1.1.1 interface Loopback1  ip vrf forwarding source  ip address 1.1.1.1 255.255.255.255  ip pim sparse-mode interface GigabitEthernet0/0/0  ip vrf forwarding source  ip address 10.1.1
