I will work just by side effect: by doing this, I will send BGP packets =66rom 89.234.186.1, which is an IP than the peer learned by BGP. This will create a recursive loop, and the session will be shut. So, no more traffic will transit through this interface, and this IP will not be displayed anymore :p --=20 alarig --qlo3tw4cmxg455lw Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJYWEq7AAoJEK84SsFrICuI9rIIAIq610fOw3KUonFG+lSBK2Qk bwu/DysUzJXLWc+0KrfDbuAxb0gtYeQSx/DcRBS234jWbruH1eDd8ODE9zirz88s PL8FGNA+kiMazUzPucMN+1flqySrS4UL1mPaL4IsO2C5An5jTAa7TciGD4Wlwan+ GZIJm9W/2UZrdg0RI6BZAtdAuaZwOqKhuWmSjL3IuyJh+ATQh5xyCjDFZIezq7MD 5gljHVJiQzwY9rGvSkvvy02Dux3CNvLLrhV5L07K50vchIf0We1pjkuOT4SQwnw0 lok/b8ny/moQv+TVcCMQHM3hPczArMH3h3K5jBjheZwW2h+YkKKRB09M2q2gVKs= =FfkW -----END PGP SIGNATURE----- --qlo3tw4cmxg455lw--
