You may have issued the command or had a device that had "no neighbor
x.x.x.x activate" on one side and not on the other. Sometimes instead
of using the cmd "neighbor x.x.x.x shutdown" some folks use accidently
when learning this per peer neighbor control feature , think activate
is the way to gracefully shut a bgp peering session . So if you have 2
devices and one of the deivces had the command "no neighbor x.x.x.x
activate" issued on one side but the other had not , you can see this
depending on the code your running also. In summary if you have that
condition you can see this message which is related to VPN4 config
setups....
