Hi, My colleague and i are struggling to originate a IPv6 BGP default route from one of our core switches to an eBGP peer. This is the configuration (below) we have tried and does work within GNS3 running the same IOS but it doesn't seem to work on o...

Hi Kanwal, yeah I was looking at this but was hoping there's another resolution with out changing the under lying infrastructure - for example the routing. Thanks for the response.

I've resolved this by removing carrier delay 30 from the physical ACE interfaces. As the ACE is connecting to the 2K where spanning-tree is not running so there is no requirement for carrier delay on the ACE.
