Bgp Analysisv0.1.1

When a BGP peer is reported down or stuck in a non-Established state, this skill helps diagnose the failure by analyzing the BGP Finite State Machine (FSM) states like Idle, Connect, or OpenSent. It checks for causes such as TCP connectivity issues, AS number mismatches, or configuration errors, enabling quick resolution to restore routing.

In cases where prefixes appear unexpectedly in routing tables, indicating a potential route leak, this skill analyzes BGP route tables to detect deviations in received prefix counts. It helps identify if upstream changes, filter misconfigurations, or new prefix origins are causing the leak, preventing network instability.

When traffic takes an unexpected path after policy changes, this skill verifies BGP path selection by walking the best-path algorithm. It examines attributes like Weight, Local Preference, AS Path length, and MED to determine why a particular route was chosen, ensuring routing policies align with expectations.

After implementing BGP configuration changes such as adding new peers or updating routing policies, this skill performs verification by checking peer states and route exchanges. It ensures that changes are applied correctly and that convergence is stable, reducing the risk of post-maintenance outages.

Following planned maintenance or unplanned failover events, this skill assesses BGP convergence speed by analyzing session inventory and route table updates. It helps identify slow convergence issues related to peer state transitions or policy application, optimizing network recovery times.
