Configuration Examples for Overlapping IP Address Pools
This section provides the following configuration examples:
• Generic IP Overlapping Address Pools Example, page 10-18
• IP Overlapping Address Pools for VPNs and VRFs Example, page 10-19
Generic IP Overlapping Address Pools Example
The following example shows the configuration of two pool groups and includes pools in the base system
group. In this example:
• Pool group grp1 consists of pools p1_g1, p2_g1, and p3_g1.
• Pool group grp2 consists of pools p1_g2 and p2_g2.
• Pools lp1 and lp2 are members of the base system group.
• The IP address 10.1.1.1 overlaps grp1, grp2, and the base system group.
• No overlapping addresses occur within any group including the unnamed base system group, which
consists of pools lp1 and lp2.
ip local pool p1_g1 10.1.1.1 10.1.1.50 group grp1
ip local pool p2_g1 10.1.1.100 10.1.1.110 group grp1
ip local pool p1_g2 10.1.1.1 10.1.1.40 group grp2
ip local pool lp1 10.1.1.1 10.1.1.10
ip local pool p3_g1 10.1.2.1 10.1.2.30 group grp1
ip local pool p2_g2 10.1.1.50 10.1.1.70 group grp2
ip local pool lp2 10.1.2.1 10.1.2.10
Note The preceding example shows pool names that provide an easy way to associate a pool name with a
group (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.
