Juniper JUNOSE 11.2.X MULTICAST ROUTING User Manual

1. Configure BGP/MPLS VPN.
host1:PE2(config-router)#router bgp 100
host1:PE2(config-router)#address-family vpnv4 unicast
host1:PE2(config-router-af)#neighbor 1.1.1.1 activate
host1:PE2(config-router-af)#neighbor 1.1.1.1 next-hop-self
host1:PE2(config-router-af)#neighbor 3.3.3.3 activate
host1:PE2(config-router-af)#neighbor 3.3.3.3 next-hop-self
host1:PE2(config-router-af)#exit-address-family
See Configuring BGP-MPLS Applications in the JunosE BGP and MPLS Configuration
Guide for details.
2. Configure PIM sparse mode in the core and RP for MVPN group addresses.
NOTE: For MVPN, it is a typical practice to use shared trees.
host1:PE1(config-router)#virtual-router PE2
host1:PE2(config)#ip multicast-routing
host1:PE2(config)#
host1:PE2(config)#! MDT RP is 72.72.72.72 (P1)
host1:PE2(config)#access-list 1 permit ip 235.0.0.0 0.255.255.255 any
host1:PE2(config)#ip pim rp-address 72.72.72.72 1
host1:PE2(config)#
host1:PE2(config)#! Do not switch from RPT for MDTs
host1:PE2(config)#ip pim spt-threshold infinity group-list 1
host1:PE2(config)#
3. Configure the loopback interface, Lp, in parent router PE2.
host1:PE2(config)#interface loopback 0
host1:PE2(config-if)#ip address 2.2.2.2 255.255.255.255
host1:PE2(config-if)#ip pim sparse-mode
host1:PE2(config-if)
NOTE: You must configure the loopback interface for PIM sparse mode to support
unnumbered MDTs.
4. Add PIM-SM to core-facing interfaces.
host1:PE2(config)#interface atm2/1.20
host1:PE2(config-subif)#ip pim sparse-mode
host1:PE2(config-subif)#
5. Extend the BGP router configuration to contribute VPN routes into the multicast
router table of the VRF using the ip route-type both command.
host1:PE2(config)#router bgp 100
host1:PE2(config-router)#address-family ipv4 unicast vrf PE21
host1:PE2(config-router-af)#ip route-type both
host1:PE2(config-router-af)#exit
host1:PE2(config-router)#
6. Configure the GRE tunnel for VPN1.
host1(config)#interface tunnel gre:MTI-21 transport-virtual-router PE2
