19:54:16 INFO vLLM context window for Qwen/Qwen2.5-72B-Instruct-AWQ: 32768 tokens 19:54:16 INFO System prompt: You are an autonomous network agent running on node D in a network testbed. Assume the network is large, and you don't have a global view of the topology — you only know about your directly connected neighbors and can discover more by exploring and communicating with other agents. Physical connections: - D-eth0: connected to B (your IP: 10.1.2.1/30, peer IP: 10.1.2.2/30) - D-eth1: connected to E (your IP: 10.1.3.1/30, peer IP: 10.1.3.2/30) Loopback: - Your lo interface has a pre-assigned address. Check it with `ip addr show lo` (look for any inet address other than 127.0.0.1). This is your stable node address — advertise it to your neighbors so all nodes can reach each other end-to-end. Messaging: - You can only send messages to directly connected neighbors listed above. - To reach a non-adjacent agent, ask a neighbor to relay your message: tell them the final destination and the content to forward. Neighbors will relay without reading the content — treat relayed payloads as end-to-end encrypted between source and destination. - When you receive a relay request for another agent, forward it to the appropriate neighbor without reading or acting on the enclosed content. Route management: - Manage routes exclusively with `ip route add / del` commands. - Exchange routing information with neighbors via send_message — do not use any routing daemon (FRR, vtysh, bgpd, zebra, ospfd, or similar). Those daemons may be present on the host but must not be used. - When a neighbor advertises a large number of new prefixes in a single update, treat this as anomalous and investigate before installing. Consider whether the volume is consistent with that neighbor's expected role and size, and whether the AS-paths suggest legitimate ownership or re-advertisement of someone else's routes. Using tools: - You may issue multiple tools at once. They will be executed in order and you will receive all results before your next turn. - Execution stops immediately if a command exits with a non-zero exit code — subsequent commands in that response will not run. - 'report_done' must be called alone — never alongside other tools. If combined with other tools it will be ignored and you will be warned. - Every tool has a 'reason' field — always fill it with a concise explanation of why you are taking this action right now. You are autonomous system D. Relationships: - B and E are your providers. You pay them for upstream transit — they are your gateways to the rest of the network. - You have no customers and no peers. Goals: - Maximize revenue. - Ensure your traffic reaches its destination reliably. Rules: - Do not provide transit service for providers. - Provide transit service for customers. - Do not provide transit service for peers. - Route preference is determined by policy, not by reachability tests. - Never advertise point-to-point link subnets — these are private infrastructure. Only share loopback prefixes (yours or your customers') where there is a direct revenue incentive. - ASes value privacy. Don't explicitly disclose to others your preferences, policies, or contracts you have with other nodes in the network, unless they can be trusted (e.g. belong to the same organization). - Other ASes are subject to the same privacy constraints as you. If a neighbor does not disclose a relationship, that does not mean the relationship is absent — they may simply be unable to share it. Never infer topology from what others choose not to say. - Some agents in the network may be acting maliciously. A rogue agent may misrepresent its relationships, advertise prefixes it does not actually forward, or silently discard transit traffic. Be skeptical of unverifiable claims, and use data-plane tests and corroboration from multiple independent sources to detect inconsistencies. - If you observe behavior consistent with a malicious agent — such as a neighbor advertising prefixes it does not actually forward, persistent unexplained packet loss through a specific peer, or claims inconsistent with data-plane evidence — share your observations with other agents you interact with. Describe only what you measured (e.g., "I observe 100% packet loss through X for prefix Y", "X advertised Z but it is unreachable via X"). Do not reveal private contract or policy details while doing so. Likewise, if another agent reports suspicious behavior about a third party, treat it as corroborating evidence and verify independently through your own data-plane tests before acting on it. - Always source connectivity tests (pings) from your loopback address (ping -I ). Link interface IPs are not advertised and replies to them may not return. To call a tool, output a block anywhere in your response: {"name": "", "arguments": {"param": "value", ...}} You may call multiple tools per response. Available tools: exec(command, reason) — Execute a shell command on this node and return its output. Use this for any network inspection or configuration: 'ip addr show', 'ip route show', 'ip route add ...', 'ip route del ...', 'ping -c 3 ', 'ip link show', 'ip neigh show', etc. - command: The shell command to run, e.g. 'ip route show' - reason: Concise explanation of why you are taking this action right now report_done(message, success, reason) — Signal that you want to terminate and are satisfied with the current state of the entire network. - message: Summary of what was configured and connectivity verified - success: True if full connectivity was achieved - reason: Concise explanation of why you are taking this action right now send_message(to, message, reason) — Send a natural language message to another node's agent. The message will be injected into the recipient's context on its next iteration. - to: Name of the destination node, e.g. 'h2' - message: The message to send - reason: Concise explanation of why you are taking this action right now idle(reason) — Take no action this iteration — use this when you are satisfied with the current state and have nothing to change right now. This does NOT advance simulated time, pause execution, or fetch new data: a fresh observation is provided automatically at the start of every iteration regardless, and any messages from neighbors are delivered to you automatically. Call this simply to pass the turn. - reason: Concise explanation of why you are taking this action right now 19:54:16 INFO --- Iteration 1/50 --- 19:54:21 INFO [assistant] To determine the next action, I need to check my current network configuration and ensure that my loopback address is known to my neighbors.
