MPLS Configuration Configuring L3 Label Switched Paths
DHCP Configuration
Note A shared network DHCP configuration will be necessary to accommodate the
example shown in
Figure 17-12 , because multiple subnets exist on a single
interface. It is also recommended that subscriber devices be configured to use the
same gateway address as cable modems; this will provide improved network
utilization when implementing a shared network architecture.
The following example shows the configuration of the DHCP server shown in Figure 17-12 to support the shared
network environment for the Internet Software Consortium (ISC):
mpls set label-switched-path dynamic2.2AOL primary dp1.2
mpls set label-switched-path dynamic2.2AOL policy AOL11.2
! Create LSP for AT&T ISP
mpls create label-switched-path dynamic3.2ATT to 1.1.1.1 no-cspf
mpls create policy ATT12.2 dst-ipaddr-mask 160.12.0.0/16
mpls set label-switched-path dynamic3.2ATT primary dp1.2
mpls set label-switched-path dynamic3.2ATT policy ATT12.2
