IP-Prefix Tunnel

IP-Prefix Tunnel

The IP-prefix tunnel function enables the creation of MPLS TE tunnels in a batch, which helps simplify configuration and improve deployment efficiency.

Background

MPLS TE provides various TE and reliability functions, and MPLS TE applications increase. The complexity of MPLS TE tunnel configurations, however, also increases. Manually configuring full-meshed TE tunnels on a large network is laborious and time-consuming. To address the issues, the HUAWEI ME60 implements the IP-prefix tunnel function. This function uses an IP prefix list to automatically establish a number of tunnels to specified destination IP addresses and applies a tunnel template that contains public attributes to these tunnels. MPLS TE tunnels that meet expectations can be established in a batch.

Benefits

The IP-prefix tunnel function allows you to establish MPLS TE tunnels in a batch. This function satisfies various configuration requirements, such as reliability requirements, and reduces TE network deployment workload.

Implementation

The IP-prefix tunnel implementation is as follows:
  1. Configure an IP prefix list that contains multiple destination IP addresses.
  2. Configure a tunnel template to set public attributes.
  3. Use the template to automatically establish MPLS TE tunnels to the specified destination IP addresses.

The IP-prefix tunnel function uses the IP prefix list to filter LSR IDs in the traffic engineering database (TEDB). Only the LSR IDs that match the IP prefix list can be used as destination IP addresses of MPLS TE tunnels that are to be automatically established. After LSR IDs in the TEDB are added or deleted, the IP-prefix tunnel function automatically creates or deletes tunnels, respectively. The tunnel template that the IP-prefix tunnel function uses contains various configured attributes, such as the bandwidth, priorities, affinities, TE FRR, CR-LSP backup, and automatic bandwidth adjustment. The attributes are shared by MPLS TE tunnels that are established in a batch.
