Non-VLT host to Non-VLT host trac ow
When VLT node receives trac from non-VLT host intended to the non-VLT host, it does neighbor entry lookup and routes trac over ICL
interface. If trac reaches wrong VLT peer, it routes the trac over ICL.
Router Solicitation
When VLT node receives router Solicitation on VLT interface/non-VLT interface it consumes the packets and will send RA back on the
received interface.
VLT node will drop the RS message if it is received over ICL interface.
Router Advertisement
When VLT node receives router advertisement on VLT interface/non-VLT interface it consumes the packets.
VLT node will drop the RA message if it is received over ICL interface.
Upgrading from Releases That Do Not Support IPv6 Peer Routing
During an upgrade to Release 9.4(0.0) from earlier releases, VLT peers might contain dierent versions of FTOS. You must upgrade both
the VLT peers to Release 9.4(0.0) to leverage the benets of IPv6 peer routing.
Station Movement
When a host moves from VLT interface to non-VLT interface or vice versa Neighbor entry is updated and synchronized to VLT peer. When
a host moves from non-VLT interface of VLT node1 to non-VLT interface of VLT node2 neighbor entry is updated and synchronized to VLT
peer.
