Using a Source Address to Demultiplex Traffic

Figure 23 on page 612 shows how you can use static subscriber interfaces to
differentiate traffic for VPN access, based on the traffic's source address.
c. Configure the primary interface to use a destination address to demultiplex
traffic. (By default, a source address is used to demultiplex traffic.)
host1(config-if)#ip demux-type da-prefix
d. Exit Interface Configuration mode.
host1(config-if)#exit
Configure subscriber interface IP1.
a. Create the shared IP interface.
host1(config)#interface ip ip1
b. Associate the shared IP interface with the layer 2 interface by using one of
the following methods:
Static
host1(config-if)#ip share-interface fastEthernet 3/1
Dynamic
host1:vr-a:vrf-1(config-if)#ip share-nexthop 10.1.1.2
c. To fully configure the shared interface, assign an address or make it
unnumbered.
host1(config-if)#ip unnumbered loopback 0
d. Specify the destination addresses for the subscriber interface to use to
demultiplex traffic.
host1(config-if)#ip destination-prefix 10.11.0.0 255.255.0.0
e. Exit Interface Configuration mode.
host1(config-if)#exit
Repeat Step 2 to configure subscriber interface IP2.
host1(config)#interface ip ip2
host1(config-if)#ip share-interface fastEthernet 3/1
host1(config-if)#ip unnumbered loopback 0
host1(config-if)#ip destination-prefix 10.12.0.0 255.255.0.0
