3. Configure the destination profile for dynamic IP tunnel creation.
host1(config)#gre destination profile pe13DataMdtProfile virtual-router pe1
host1(config-dest-profile)#tunnel source 1.1.1.1
host1(config-dest-profile)#tunnel destination ip subnet 233.3.0.0/16
host1(config-dest-profile)#tunnel mdt profile pe1DataMdtMdt
host1(config-dest-profile)#profile pe13DataMdtMti
host1(config-dest-profile)#exit
The router uses this destination profile to verify whether it can create a dynamic
tunnel, and to supply additional configuration parameters when it creates a tunnel.
For more information about creating dynamic IP tunnels, see Configuring Dynamic
IP Tunnels in the JunosE IP Services Configuration Guide.
4. Configure the group address pools in the route map.
host1(config)#virtual-router pe1
host1:pe1(config)#ip pim group-address-pool pe13DataMdtGroups 233.3.1.0
233.3.1.255
If the data MDTs are established using ASM, you must divide the range of available
MDT P-Group addresses so that PEs source VPN multicasts. All VRFs in a PE draw
from a single address pool that contains the range of group addresses assigned to
that PE.
If the data MDTs are established using SSM, you can configure VRFs to transmit on
a tunnel using the same MDT P-Group address. Each VRF transmits using a unique
P-Source address; however, each data MDT created by the VRF must use a different
P-Group address. There might be one sender data MDT and possibly many receiver
data MDTs sharing an IP tunnel.
For SSM, each PE can assign MDT P-Groups from the same range, but the P-Group
addresses must be administratively divided among the VPNs as mentioned in the
following example:
host1(config)#virtual-router pe1
host1:pe1(config)#ip pim group-address-pool pe11DataMdtSSMGroups 233.3.1.0
233.3.1.255
host1:pe1(config)#ip pim group-address-pool pe12DataMdtSSMGroups 233.3.2.0
233.3.2.255
host1:pe1(config)#ip pim group-address-pool pe13DataMdtSSMGroups 233.3.3.0
233.3.3.255
5. Configure the access list to match <S,G> and <*,G> entries.
host1:pe1(config)#virtual-router pe1:pe13
host1:pe1:pe13(config)#access-list pe13DataMdtSend permit ip host 10.13.0.100
225.1.1.0 0.0.0.255
host1:pe1:pe13(config)#access-list pe13DataMdt permit ip any 225.1.0.0 0.0.255.255
6. Specify a route map to configure the set of <S, G> for which data MDTs can be
created, and the threshold to be applied for each SG.
host1:pe1:pe13(config)#route-map pe13MdtThresholds permit 10
