Hello @brian-s-cao
Thank you for your contribution!
I'm a volunteer and at a broad level there are a few things necessary to make this successful.

• Please submit one template per pull request (PR).
• General contributing guidelines.
• Test data is necessary for most (if not all) contributions to confirm with a high certainty that no regressions and unintended breakage occurs.
• Helper scripts exist to make the creation of the structured data simple, but still require the contributor to review so the output is as intended.
  • Details on building a dev environment

Hello @brian-s-cao

• We want one template per pull request to make it easier promptly review and test.
• One template per PR gives you the opportunity to apply suggested improvements to other templates/files based on the first one or two the maintainers review.

Would you be able to please reduce this PR down to the huawei_vrp_display_bgp_peer template with its related index update and test data?
