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
host1(config-if)# tunnel source 2.2.2.2
host1(config-if)# tunnel destination 235.1.1.1
host1(config-if)# tunnel mdt
