Autoconfiguration

Pathvector can build certain peer configurations automatically. The match command finds common IXPs for an ASN and outputs a plaintext email body or a Pathvector YAML snippet.

YAML Config​

Generated YAML output will be indented 2 spaces by default to fit within the YAML peers key. Plaintext output is selected by default, add the --generate-config|-g flag to select YAML generation mode.

Arbitrary ASN​

The first ASN will be read from the pathvector.yml config file by default, but you can supply an alternate ASN with the --local-asn|-l flag if you want to find common IXPs for two arbitrary networks.
