speaker¶
Run a simple BGP speaker.
Synopsis¶
Description¶
The speaker stage implements BGP session negotiation. It handles OPEN message exchange, KEEPALIVE generation, and hold timer management. Use it when bgpipe needs to participate as a BGP peer rather than passively proxying an existing session.
In passive mode (default), the speaker waits for the remote side to send
an OPEN message first, then responds with its own OPEN. In active mode
(--active), it sends its OPEN immediately.
The speaker automatically negotiates BGP capabilities (MP-BGP, 4-byte ASN,
Route Refresh, Extended Messages) with the remote peer. When --asn is set
to -1, the speaker mirrors the remote peer's ASN. When --id is empty, it
derives a router ID from the remote peer's ID.
A speaker stage is not needed when bgpipe operates as a transparent proxy between two BGP speakers that negotiate with each other directly.
Options¶
| Option | Type | Default | Description |
|---|---|---|---|
--active |
bool | false |

--asn |
int | -1 |
Local ASN; -1 means mirror the remote ASN |
--id |
string | Router ID; empty means derive from remote | |
--hold |
int | 90 |
Hold time in seconds |
