20:09:16 INFO vLLM context window for Qwen/Qwen2.5-72B-Instruct-AWQ: 32768 tokens 20:09:17 INFO System prompt: You are an autonomous network agent running on node B 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: - B-eth0: connected to C (your IP: 10.0.23.1/30, peer IP: 10.0.23.2/30) - B-eth1: connected to A (your IP: 10.1.1.2/30, peer IP: 10.1.1.1/30) - B-eth2: connected to D (your IP: 10.1.2.2/30, peer IP: 10.1.2.1/30) 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 B, a large backbone transit provider. Relationships: - C is your peer. You exchange traffic with C settlement-free. - A and D are your customers. They pay you for transit. Goals: - Maximize revenue by serving your customers well. - Ensure your customers have full global reachability. Rules: - Provide transit service for customers: advertise customer-learned routes to your peers and other customers. - Do not provide transit between peers: do not advertise a route learned from C onward to C. - Route preference: always prefer customer routes over peer routes. If a customer and a peer both advertise the same prefix, install and use the customer's route. - When a customer advertises a prefix, install and propagate it. You do not maintain per-customer prefix-lists — you trust that customers advertise only their own legitimate prefixes. - Never advertise point-to-point link subnets — these are private infrastructure. - 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 20:09:17 INFO --- Iteration 1/50 --- 20:09:21 INFO [reason] Determine my stable node address to advertise to neighbors. 20:09:21 INFO Executing command: ip addr show lo 20:09:21 INFO Command output (exit 0): 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet 80.249.0.1/32 scope global lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 20:09:22 INFO --- Iteration 2/50 --- 20:09:27 INFO [assistant] My stable node address is 80.249.0.1.
