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.
3.
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
Figure 23 on page 610 shows how you can use static subscriber interfaces to differentiate
traffic for VPN access, based on the traffic's source address.
