Example for Configuring EVPN VPWS over SRv6 TE Policy (Manual Configuration)
This section provides an example for configuring an SRv6 TE Policy to carry EVPN VPWSs.
Networking Requirements
On the network shown in Figure 1, PE1, the P, and PE2 are in the same AS and run IS-IS to implement IPv6 network connectivity. It is required that a bidirectional SRv6 TE Policy be deployed between PE1 and PE2 to carry EVPN VPWSs.
Configuration Roadmap
The configuration roadmap is as follows:
Enable IPv6 forwarding and configure an IPv6 address for each interface on PE1, the P, and PE2.
Enable IS-IS, configure an IS-IS level, and specify a network entity title (NET) on PE1, the P, and PE2.
Configure EVPN VPWS and EVPL instances on each PE and bind the EVPL instance to an access-side sub-interface.
Establish a BGP EVPN peer relationship between PEs.
- Configure SRv6 SIDs and enable IS-IS SRv6 on PE1, the P, and PE2. In addition, configure PE1 and PE2 to advertise VPN routes carrying SIDs.
Configure an SRv6 TE Policy on PE1 and PE2.
- Configure a tunnel policy on PE1 and PE2 to import VPN traffic.
Data Preparation
To complete the configuration, you need the following data:
IPv6 address of each interface on PE1, the P, and PE2
IS-IS process ID of PE1, the P, and PE2
IS-IS level of PE1, the P, and PE2
EVPN instance name: evrf1
RD and RT of the EVPN instance
Procedure
- Enable IPv6 forwarding and configure an IPv6 address for each interface.
# Configure PE1. The configurations of the P and PE2 are similar to the configuration of PE1. For configuration details, see Configuration Files in this section.
