RFC3069 example setup for Cisco

[Mikael Abrahamsson]

Got a few requests to provide RFC3069-style config for cisco, so here it 
is:

int lo1
ip address 192.168.100.1 255.255.255.0

int vlan100
ip address unnumbered lo1
ip local-proxy-arp
int vlan101
ip address unnumbered lo1
ip local-proxy-arp
int vlan101
ip address unnumbered lo1
ip local-proxy-arp

ip route 192.168.100.2 vlan 100
ip route 192.168.100.3 vlan 101
ip route 192.168.100.4 vlan 102

Provides L2 separation for customers but still use a single IP subnet.
