Creating Multicast VPNs
host1(config-if)#exit
host1(config)#
Configure the GRE tunnel for VPN2
host1(config)#interface tunnel gre:MTI-22 transport-virtual-router PE2
thost1(config-if)#tunnel source 2.2.2.2
host1(config-if)#tunnel destination 235.1.1.2
host1(config-if)#tunnel mdt
host1(config-if)#exit
host1(config)#
Configure the IP interface (Tv) in PE2:CE1 as a PIM sparse-mode interface with
the address of the loopback interface.
host1(config)#virtual-router PE2:CE21
host1:PE2:CE21(config)#interface tunnel gre:MTI-21
host1:PE2:CE21(config)#ip address 2.2.2.2 255.255.255.255
host1:PE2:CE21(config)#ip pim sparse-mode
host1:PE2:CE21(config)#exit
host1:PE2:CE21#
Configure the IP interface (Tv) in PE2:CE2 as a PIM sparse-mode interface with
the address of the loopback interface (same as the loopback 0 address for PE2).
host1:PE2:CE21(config)#interface loopback 0
host1:PE2:CE21(config-if)#ip address 2.2.2.2 255.255.255.255
host1:PE2:CE21(config-if)#exit
host1:PE2:CE21(config)#exit
host1:PE2:CE21#virtual-router PE2:CE22
host1:PE2:CE22#configuration terminal
host1:PE2:CE22(config)#interface tunnel gre:MTI-22
host1:PE2:CE22(config)#ip unnumbered loopback 0
host1:PE2:CE22(config)#ip pim sparse-mode
host1:PE2:CE22(config)#exit
host1:PE2:CE22#
Configure the Tp interfaces as unnumbered IP interfaces.
host1(config)#interface tunnel gre:MTI-21.mdt
host1(config-if)#ip unnumbered loopback 0
host1(config-if)#ip pim sparse-mode
host1(config-if)#exit
host1(config)#
host1(config)#interface tunnel gre:MTI-22.mdt
host1(configif)#ip unnumbered loopback 0
host1(config-if)#ip pim sparse-mode
host1(config-if)#exit
host1(config)#
Use to enable multicast distribution tree operation so the IP tunnel component
can create an MDT interface. This command functions for GRE interfaces only.
