Creating a Profile for Dynamic Interfaces

You can create a profile by using CLI commands similar to those used to create the equivalent static interfaces. You can configure a profile for bridged Ethernet, IP, IPv6, MLPPP, PPP, PPPoE, or VLAN interfaces.

To configure a profile:

1. Create a profile by assigning it a name.
   host1(config)#profile foo
2. Specify a virtual router to which to assign dynamic IP interfaces created with this profile.
   host1(config-profile)#ip virtual-router egypt
3. Specify an IP loopback interface for dynamic IP interfaces created with this profile to be associated.
   host1(config-profile)#ip unnumbered loopback 0
4. Configure IPCP option 0x90.
   host1(config-profile)#ppp ipcp netmask
5. Optionally set IP, IPv6, MLPPP, PPP, or PPPoE characteristics. For more information, see Configuring Profile Characteristics .

   Note: When configuring either IP or IPv6 to operate over PPP, you might want to initiate IP or IPv6 by using the appropriate ppp initiate command, either ppp initiate-ip or ppp initiate-ipv6. This command initiates either IPv4 or IPv6 in the event you are connecting to a passive client.
