IP Overlapping Address Pools for VPNs and VRFs Example

The following example is a general IP address configuration that VPNs and VRFs might use. This
example shows pool names that provide a way to associate a pool name with a VPN (when the pool name
stands alone). This association is an operational convenience. There is no required relationship between
the names used to define a pool and the name of the group. In this example:
•

OL-2226-23
Pool group vpn1 consists of pools p1_vpn1, p2_vpn1, and p3_vpn1.
Pool group vpn2 consists of pools p1_vpn2, p2_vpn2.
Pools lp1 and lp2 are members of the base system.
The IP address 10.1.1.1 overlaps vpn1, vpn2, and the base system group.
No overlapping addresses occur within any group including the unnamed base system group, which
consists of pools lp1 and lp1.
ip local pool p1_vpn1 10.1.1.1 10.1.1.50 group vpn1
ip local pool p2_vpn1 10.1.1.100 10.1.1.110 group vpn1
ip local pool p1_vpn2 10.1.1.1 10.1.1.40 group vpn2
ip local pool lp1 10.1.1.1 10.1.1.10
ip local pool p3_vpn1 10.1.2.1 10.1.2.30 group vpn1
ip local pool p2_vpn2 10.1.1.50 10.1.1.70 group vpn2
ip local pool lp2 10.1.2.1 10.1.2.10
