Example for Configuring an RSVP-TE over GRE Tunnel
Networking Requirements
On the network shown in Figure 1, OSPF runs on DeviceB, DeviceC, and DeviceD, and a GRE tunnel is established between DeviceB and DeviceD. A TE tunnel with 10 Mbit/s bandwidth is required between DeviceA and DeviceE. The maximum reservable link bandwidth of the tunnel is 10 Mbit/s, as is the BC0 bandwidth.
Configuration Precautions
In this example, an RSVP-TE over GRE tunnel is configured, and the GRE tunnel interfaces cannot borrow the IP addresses of other interfaces. During configuration, you can enable an IGP on GRE tunnel interfaces and configure MPLS link attributes.
Configuration Roadmap
The configuration roadmap is as follows:
Assign an IP address to each interface, including the loopback interface whose address is to be used as an LSR ID on each involved node.
- Configure OSPF on DeviceB, DeviceC, and DeviceD, and establish a GRE tunnel between DeviceB and DeviceD.
Enable IS-IS globally, configure a network entity title (NET), specify the cost type, and enable IS-IS TE. Enable IS-IS on each interface (including loopback interfaces and GRE tunnel interfaces).
Configure MPLS LSR-IDs, and enable MPLS, MPLS TE, MPLS RSVP-TE, and MPLS CSPF globally.
Enable MPLS, MPLS TE, and MPLS RSVP-TE on each interface.
Configure the maximum reservable link bandwidth and BC bandwidth on the outbound interfaces of each involved tunnel.
Create a tunnel interface on the ingress and configure an IP address, tunnel protocol, destination IP address, and tunnel bandwidth.
Data Preparation
To complete the configuration, you need the following data:
IS-IS area ID, originating system ID, and IS-IS level of each node
Maximum bandwidth and maximum reservable bandwidth for each link along the tunnel
Tunnel interface number, IP address, destination IP address, tunnel ID, and tunnel bandwidth
Procedure
- Configure an IP address for each interface.
Assign an IP address and a mask to each interface according to Figure 1. The configuration details are not provided.
- Establish a GRE tunnel between DeviceB and DeviceD.
