How to use this index
- Accepted policy authority lives in accepted ADRs (for example adr-019-hybrid-network-rollout-aci-a-ai-only-evpn-b-target, adr-018-network-validation-ansible-vendor-cli, and adr-007-ip-addressing-2026).
- Working direction for pending policy areas lives in draft ADRs (adr-020-backbone-service-vs-transport-l3vpn-sr-mpls, adr-021-dc-evpn-to-backbone-l3vpn-interconnect, and adr-023-ipv6-numberplan-and-cluster-scale-strategy) until those ADRs are accepted.
- Architecture contracts live in Network Architecture and linked baseline notes.
- Implementation procedures and worked examples live in network topic notes.
