Nokia Models¶

Comprehensive documentation for Nokia SROS YANG models in the workspace.

Overview¶

Nokia SROS (Service Router Operating System) provides YANG models for network configuration and management. This workspace includes the core BGP-related models and their dependencies.

Source Repository: Nokia 7x50 YANG Models
Local Path: nokia/
Symlink Location: models/nokia/
Version: SROS 25.7 (Latest)

🆕 Latest Updates¶

✅ Upgraded to SROS 25.7 - Latest Nokia version with newest BGP features
✅ Added Configuration Models - Both state and configuration models available
✅ Enhanced Validation - Improved validation with proper dependencies
✅ Better Organization - Cleaner model structure and documentation

Available Models¶

BGP State Models (Monitoring & Telemetry)¶

`nokia-state-router-bgp.yang`¶

Description: BGP operational state model for monitoring and telemetry
Location: models/nokia/bgp/nokia-state-router-bgp.yang
Version: SROS 25.7
Status: ✅ Validated (types), ⚠️ Complex dependencies (expected)

Key Features: - BGP neighbor operational state - BGP session statistics and counters - Route table information - BGP policy application state - Performance metrics and monitoring data

`nokia-state.yang`¶

Description: Main Nokia state model (includes BGP submodule)
Location: models/nokia/common/nokia-state.yang
Version: SROS 25.7
Status: ⚠️ Complex dependencies (expected for full model)

BGP Configuration Models (Device Management)¶

`nokia-conf-router-bgp.yang`¶

Description: BGP configuration model for device configuration
Location: models/nokia/config/nokia-conf-router-bgp.yang
Version: SROS 25.7
Status: ✅ Available, ⚠️ Complex dependencies (expected)

Key Features: - BGP global configuration - Neighbor configuration and policies
- Route filtering and redistribution - BGP communities and extended communities - Multi-protocol BGP support (IPv4, IPv6, VPN) - Administrative state controls

For detailed configuration examples and comparisons with OpenConfig, see BGP Configuration Model Comparison.

`nokia-conf.yang`¶

Description: Main Nokia configuration model (includes BGP submodule)
Location: models/nokia/config/nokia-conf.yang
Version: SROS 25.7
Status: ⚠️ Complex dependencies (expected for full model)

Type Definitions (Standalone & Validated)¶

`nokia-types-bgp.yang`¶

Description: BGP-specific type definitions
Location: models/nokia/types/nokia-types-bgp.yang
Version: SROS 25.7
Status: ✅ Fully Validated

`nokia-sros-yang-extensions.yang`¶

Description: Nokia SROS YANG extensions and annotations
Location: models/nokia/types/nokia-sros-yang-extensions.yang
Version: SROS 25.7
Status: ✅ Fully Validated

Validation Status¶

✅ Types and Extensions: Fully validated standalone
✅ State Models: Available with expected complex dependencies
✅ Configuration Models: Available with expected complex dependencies
✅ Version: Latest SROS 25.7

Usage Examples¶

# Validate Nokia BGP types (works standalone)
pyang --strict --path nokia/types:ietf nokia/types/nokia-types-bgp.yang

# Analyze Nokia BGP state structure  
pyang -f tree --tree-depth 3 nokia/bgp/nokia-state-router-bgp.yang

# Analyze Nokia BGP config structure
pyang -f tree --tree-depth 3 nokia/config/nokia-conf-router-bgp.yang

Model Dependencies¶

Nokia BGP models have several dependencies that are automatically handled by the project setup:

Required Dependencies¶

IETF Standards: - ietf-yang-types.yang - Standard YANG types - ietf-inet-types.yang - Internet address types

Nokia Specific: - nokia-types-bgp.yang - BGP-specific types - nokia-types-router.yang - Router types - nokia-types-services.yang - Service types - nokia-sros-yang-extensions.yang - Nokia YANG extensions

Validation¶

# Run validation (from models directory)
./validate-bgp.sh

# Expected output:
# 📋 Nokia SROS BGP Types (Standalone Models):
#   ✅ Nokia BGP types: VALID
#   ✅ Nokia SROS extensions: VALID

Notes¶

Complex Dependencies: Full BGP models (state and config) have complex interdependencies which is normal for enterprise networking models
Standalone Validation: Type definitions and extensions validate successfully as standalone models
Latest Version: All models use SROS 25.7 for access to the newest BGP features and fixes
