Dynamic resizing of IP address pools, increasing or reducing the size of the pool as needed
Automated control of address assignment
Easy monitoring capabilities, enabling the pool manager to assess address utilization
Support for MPLS VPNs with addresses assigned per subnet, per interface (see the
Address Pools for MPLS VPNs" section on page
Simplified VPN setup, enabling the pool manager to request an initial subnet from the address pool
server upon configuration of the on-demand address pool (ODAP)
You can choose to specify a VRF for an ODAP. If you do, you must configure the VRF first and then
configure the VRF in the ODAP. If you do not configure a VRF in the pool, the pool is assumed to
be in the global address space.
The VRF of the PPP session must match the VRF configured in the pool. To ensure that it does,
configure a virtual template interface using the ip vrf forwarding command. If you use AAA to
authorize the PPP user, you can include the VRF in the user profile configuration on the RADIUS
server.
