# WHATPORT(2605)

## NAME

port 2605 — FRRouting/Quagga bgpd vty — The BGP daemon's command line — the next port up from ospfd on an FRR router.

Protocol: TCP  
IANA: nsc-posa

## DESCRIPTION

2605 is BGP_VTY_PORT in FRRouting: bgpd's own telnet-style management CLI, separate from every other daemon's. Anyone who gets past its password can read the full BGP table and change neighbors, policy, and redistribution on a live router. It shows up on Linux route servers and reflectors, and on FRR-based network appliances. IANA has 2605 registered as "NSC POSA", unrelated to routing.

## EXPOSURE

**Do not expose.** This is the routing control plane over cleartext telnet — internet exposure hands over the router's BGP configuration.

## CHECK

```sh
nc -v -w 3 TARGET 2605
```
