To borrow an IP address on unnumbered PPP from the vlan2 interface, use the
following commands:

configure terminal
awplus(config)#
interface vlan2
awplus(config-if)#
ip address 6.6.6.6/24
awplus(config-if)#
exit
awplus(config)#
interface ppp0
awplus(config-if)#
ip unnumbered
vlan2
To remove the borrowed IP address, use the following commands:
awplus#
configure terminal
awplus(config)#
interface ppp0
awplus(config-if)#
no ip unnumbered
To verify borrowed address is configured on PPP interface
ppp0
, use the following
command:
