I believe the issue below was reported by a few readers and perhaps even in the discussion forums. In any case the release notes offer two workarounds and suggest the problem is not evident in 6.1.2 software.
With SMLT configured, the default route was learned on an incorrect port after core stack reboot (Q02123318)
Is issue is only partially fixed in 6.0.5, not reproducible with 6.1.2. There are two workarounds:
– clear the arp-cache
– Configure VLACP on the IST ports.
As always I would strongly suggest you review the release notes for yourself.
