AI-Powered Network Remediation Advanced

The ultimate goal of AI-assisted network automation is self-healing infrastructure. By combining AI diagnostics with Ansible's execution capabilities, you can build systems that detect problems, determine root causes, generate remediation playbooks, and execute fixes — with appropriate human oversight.

The Remediation Loop

An AI-driven remediation system operates in a continuous loop that monitors, detects, diagnoses, and resolves network issues:

Monitor and detect
Network monitoring tools (Nagios, Zabbix, Prometheus) detect an anomaly or failure condition and trigger an alert.
Gather diagnostic data
Ansible playbooks collect relevant data: show commands, logs, interface status, routing tables, and resource utilization.
AI diagnosis
The collected data is sent to an LLM that analyzes the symptoms, correlates events, and identifies the likely root cause.
Generate remediation playbook
Based on the diagnosis, AI generates an Ansible playbook to fix the identified issue.
Validate and execute
The remediation playbook is validated (AI + lint) and executed, with results verified automatically.

Building a Remediation Engine

Python

import anthropic
import subprocess
import json

class NetworkRemediator:
    def __init__(self):
        self.client = anthropic.Anthropic()
        self.approved_actions = ["interface_reset",
            "bgp_clear", "route_refresh"]

    def diagnose(self, alert_data, device_output):
        """Send diagnostic data to AI for root cause analysis"""
        response = self.client.messages.create(
            model="claude-sonnet-4-20250514",
            max_tokens=2000,
            messages=[{
                "role": "user",
                "content": f"""Analyze this network alert and device output.
Alert: {json.dumps(alert_data)}
Device output: {device_output}

Provide:
1. Root cause analysis
2. Severity (critical/high/medium/low)
3. Recommended Ansible remediation playbook
4. Verification commands to confirm fix"""
            }]
        )
        return response.content[0].text

    def execute_remediation(self, playbook_path):
        """Execute validated remediation playbook"""
        result = subprocess.run(
            ["ansible-playbook", playbook_path, "--check"],
            capture_output=True, text=True
        )
        if result.returncode == 0:
            # Dry run passed, execute for real
            return subprocess.run(
                ["ansible-playbook", playbook_path],
                capture_output=True, text=True
            )
        return result

Safety Guardrails

Critical: Never allow fully autonomous remediation on production networks without human approval gates. Start with dry-run mode, move to auto-remediation only for well-understood, low-risk scenarios.

Risk Level	Automation Level	Example Actions
Low	Fully automated	Clear interface counters, refresh ARP cache
Medium	Auto with notification	Reset BGP session, bounce interface
High	Human approval required	Routing table changes, ACL modifications
Critical	Manual only	Firmware upgrades, core device changes

Example: BGP Peer Down Remediation

When a BGP peer goes down, the remediation engine can automatically collect show commands, diagnose the issue (interface down, authentication mismatch, route limit exceeded), and generate the appropriate fix.

YAML

# AI-generated remediation playbook for BGP peer reset
---
- name: Remediate BGP peer down - Router R1
  hosts: r1.core.example.com
  gather_facts: no

  tasks:
    - name: Check interface status
      cisco.ios.ios_command:
        commands:
          - show interface GigabitEthernet0/1
      register: intf_status

    - name: Reset interface if down
      cisco.ios.ios_interfaces:
        config:
          - name: GigabitEthernet0/1
            enabled: true
        state: merged
      when: "'down' in intf_status.stdout[0]"

    - name: Clear BGP session
      cisco.ios.ios_command:
        commands:
          - clear ip bgp 10.0.0.2 soft

    - name: Verify BGP peer state
      cisco.ios.ios_command:
        commands:
          - show ip bgp summary
      register: bgp_verify

Try It Yourself

Design a remediation workflow for a common network issue in your environment. Define the alert trigger, diagnostic data collection, and the AI prompt for generating the fix.
