Configuration Roadmap
The configuration roadmap is as follows:
1. Assign IP addresses to interfaces on each node and configure the loopback addresses that
are used as LSR IDs.
2. Enable IS-IS.
3. Configure the policy for aggregating routes.
4. Enable global and interface-based MPLS and MPLS LDP on each node.
5. Configure LDP Extension for Inter-Area LSP.
Data Preparation
To complete the configuration, you need the following data:
l IP address of each interface, as shown in Figure 2-13
l IS-IS area ID of each nodes and levels of each nodes and interfaces
Procedure
Step 1 Assign IP addresses to interfaces on each node and configure the loopback addresses that are
used as LSR IDs.
As described in Figure 2-13, configure an IP address and a mask for each interface, including
a loopback interface. The configuration details are not mentioned here.
Step 2 Enable IS-IS.
