I lost track of the discussions in the past (sorry) but want to revisit this to understand what was the limitation because it should also affect gre(8) and other tunnel pseudo-interfaces. -- Hiroki ----Security_Multipart(Tue_Jun_23_03_29_31_2020_442)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- iMkEABMKAC4WIQRsDSNTJ8+Ax5Ae/dLbsH3Gbx9zfwUCXvD4ixAcaHJzQGZyZWVi c2Qub3JnAAoJENuwfcZvH3N/34wCCPQlRaFUvA7SPSPnVqom0duXc6QlmAlvCSgY r0tek1uOaXZ9aQD6HjvnnolbkYHYC0BDIqmVy3kvNLspuV2BLxOMAgkBqo/MtTDm pnSXCmouduJvif7ktmD83NvmIzQNfkgN1IyFpbcjWADu7uqYBjv37k7I7Hc0vIp4 aWn0N+1AAeA3HYw= =lCt/ -----END PGP SIGNATURE----- ----Security_Multipart(Tue_Jun_23_03_29_31_2020_442)----
