This means that remote side received an attribute (from us) and don't like its flags. To me the flags seems OK, It is community attribute (08 in second byte) and has flags optional+transitive+ext_length (d0), which is correct. The attribute is pretty big (272 bytes, 68 communities). Perhaps the other side has bad impelmentation of BGP that does not know ext_length flag (that seems likely because just first four bytes of the attribute are shown, instead of full 272 bytes). -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
