Nope. According to http://www.iana.org/assignments/bgp-parameters/bgp-parameters.xhtml subcode 8 is not specified. So I guess that 194.68.129.153 is somewhat strange aka. broken. You could try to play with announce as-4byte no announce refresh no and maybe announce capabilities no Would like to know what kind of system that is. > group Sfinx { > local-address 194.68.129.xxx > announce all > announce IPv4 unicast > announce IPv6 none > softreconfig in yes > softreconfig out yes > set med 50 > set localpref 5500 > depend on vlan2 > enforce neighbor-as yes > > ... > > neighbor 194.68.129.153 { > remote-as 21409 > max-prefix 50 restart 60 > set community delete 21409:* > } > } > > Thanks > > /Xavier > -- :wq Claudio
