Has anyone seen this behavior with BGP IPv6 between Juniper (owned by Level 3, advertising routes correctly, sending default ::/0) and Cisco (6509 running 12.2.58.SXI6 advipservices, receiving all routes fine except default, hearing ::/3)? I worked with Level 3 and they confirmed they are sending ::/0 as default:
Just stab in the dark. Verify that you're not disagreeing on SAFI. If JNPR is sending labeled SAFI and you are expecting to receiving unlabeled unicast SAFI. Then '3' from JNPR as 'implict null' would to you mean prefix lenght. Obviously it should fail harder, but I've seen IOS<->IOS reporting SAFI to be one, but coding NLRI as if SAFI was something else. -- ++ytti
