  • Add wiki link validation system and fix 286 broken internal links Added comprehensive link validation to prevent committing broken wiki links: **New validation system:** - scripts/validate-wiki-links.py - Validates all internal wiki links - scripts/fix-wiki-links.py - Auto-fixes common link format issues - .git/hooks/pre-commit - Git hook to block commits with broken links - scripts/README.md - Complete documentation - scripts/USAGE.md - Quick start guide **Link fixes applied (286 fixes across 62 files):** - Fixed GitHub wiki link format (removed directory prefixes) - Changed [Text](Getting-Started-Quick-Start) → [Text](Quick-Start) - Changed [Text](Use-Cases-DDoS-Mitigation) → [Text](DDoS-Mitigation) - Changed [Text](Address-Families-FlowSpec-FlowSpec-Overview) → [Text](FlowSpec-Overview) **Validation status:** - Before: 797 broken links in 67 files - After: 300 broken links in 26 files (mostly links to non-existent files) - Improvement: 63% reduction in broken links **How the system works:** 1. Pre-commit hook runs automatically on `git commit` 2. Validates all staged markdown files 3. Blocks commits if broken links found 4. Can be bypassed with `--no-verify` (not recommended) **Remaining errors:** - Links to files that don't exist yet (Health-Checks.md, Environment-Variables.md, etc.) - These will need to be created or removed - Anchor warnings (non-critical, won't block commits) **Usage:** ```bash # Check for broken links python3 scripts/validate-wiki-links.py # Auto-fix links python3 scripts/fix-wiki-links.py # Commit (hook runs automatically) git commit -m "message" ``` Note: Using --no-verify for this commit because some links point to files that don't exist yet. Future commits will be validated automatically. 👻 Ghost written by Claude (Anthropic AI)

  • Documentation: Feature built-in healthcheck module throughout docs Make ExaBGP's built-in 'exabgp healthcheck' tool prominent and easy to discover. Changes: - Quick-Start.md: Replace generic health check note with prominent built-in module callout showing zero-code example with rise/fall dampening - Home.md: Add "Zero-Code Health Checks Built-In!" section with example command and triple-star highlight in Tools section - Installation-Guide.md: Add "Test Built-in Healthcheck Module" verification step and feature in Next Steps - Service-High-Availability.md: Add prominent recommendation callout for built-in module at top of Health Check Strategies section - _Sidebar.md: Add starred Healthcheck Tool link directly in Getting Started section The built-in healthcheck module provides production-ready features: - Rise/fall dampening to avoid flapping - Automatic IP address management with label matching - Metric-based failover (MED values) - Execution hooks for alerts - Syslog integration - Configuration file support Users no longer need to write custom health check scripts for 90% of use cases. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

  • Documentation: Correct HAProxy/load balancer architecture explanation Changes to Use-Cases-Service-High-Availability.md (both versions): Corrected misleading statement about HAProxy requiring Layer 2 connectivity. REALITY: - HAProxy/NGINX work across Layer 3 (no Layer 2 requirement) - The REAL limitation: Load balancers are CENTRALIZED devices - Cannot span multiple data centers without becoming SPOF - If the DC with the load balancer fails, entire service fails ExaBGP's actual advantage: - Distributed architecture (no central device) - Can span multiple data centers - Survives entire DC failure - BUT: Slower failover (5-15s vs <1s) COMMON USE CASE: ExaBGP provides resilience TO load balancers - HAProxy-DC1 + ExaBGP announces VIP - HAProxy-DC2 + ExaBGP announces VIP - If DC1 fails, traffic automatically routes to DC2 Combined architecture (best of both): ExaBGP → Distribute across DCs (geographic redundancy) ↓ HAProxy/NGINX in each DC → Fast local failover (<1s) ↓ Backend servers Addresses user feedback: "HAProxy can work with layer 3 but it require a central device for the traffic which can not be in two DC, exabgp can be used to provide resilience to balancers" 👻 Ghost written by Claude (Anthropic AI) Co-Authored-By: Claude <[email protected]>

  • Documentation: Correct BGP load balancing limitations Major corrections to Load-Balancing.md and Service-High-Availability.md (both versions): 1. BGP CANNOT do proportional/weighted traffic distribution: - BGP + ECMP provides EQUAL distribution (not weighted) - MED is for primary/backup selection (not proportional distribution) - Lower MED receives ALL traffic, not "more" traffic - No way to make one server receive "50%" or "twice as much" traffic 2. Corrected "Metric-Based Health" section: - Renamed to "Load-Based Health Checks" - Added warning: BGP is binary (announce or withdraw) - Withdrawing route breaks TCP connections - Use HIGH thresholds (95% CPU) to avoid disruption - NOT suitable for proportional load balancing 3. Corrected "Weighted Load Distribution" section: - Renamed to "Proportional Load Distribution (NOT Possible with BGP Alone)" - Removed misleading MED-based weighted examples - Explained what CAN be done (ECMP equal, load-based withdrawal, multi-IP) - Recommended Layer 7 load balancers (HAProxy/NGINX) for weighted distribution - Documented multi-tier architecture as correct approach 4. For weighted/proportional load balancing, use: - Layer 7 Load Balancer (HAProxy, NGINX) with weighted backends - Multi-tier: ExaBGP → L4 LB → Layer 7 weighted distribution Addresses user feedback: "you can not partial route via BGP it is an all or nothing" 👻 Ghost written by Claude (Anthropic AI) Co-Authored-By: Claude <[email protected]>

  • Documentation: Remove impractical multi-cloud BGP claim Changes to Use-Cases-Service-High-Availability.md (both flat and hierarchical): Removed misleading claims about "different cloud providers" and "multi-cloud deployments". Reality: - Multi-cloud BGP requires public BGP announcements (typically /24 minimum) - Not practical for most use cases due to IPv4 scarcity and BGP routing table growth - ExaBGP works best within a single network/AS where internal BGP can be used Corrected geographic scope to: - Different racks in same data center - Different data centers in same region - Different regions (within same autonomous system) Added note explaining multi-cloud limitations and why it's not recommended. Addresses user feedback about multi-cloud BGP practicality. 👻 Ghost written by Claude (Anthropic AI) Co-Authored-By: Claude <[email protected]>

  • Documentation: Correct HA failover speed comparison Changes to Use-Cases-Service-High-Availability.md (both flat and hierarchical): Corrected misleading comparison of failover speeds: - HAProxy/NGINX: Very fast local failover (< 1 second), but LIMITED to Layer 2 - ExaBGP: 5-15 seconds BGP convergence, works across ANY IP-reachable location - DNS-based HA: 30-60 seconds (DNS TTL) Key point: ExaBGP's value is geographic redundancy WITHOUT Layer 2 dependency. Traditional L7 load balancers are faster locally but cannot span geographic zones without Layer 2 connectivity (VPN/tunneling). ExaBGP enables true Layer 3 routing-based failover across: - Different racks - Different data centers - Different regions - Different cloud providers - Multi-cloud deployments Addresses user feedback that HAProxy can failover faster than indicated. 👻 Ghost written by Claude (Anthropic AI) Co-Authored-By: Claude <[email protected]>
