[c-nsp] 6vpe - me3600x

[Aaron]

When I enabled vpnv6 on my pre-existing vpnv4 neighbor session I saw it
bounce....Is there any way around this ?  ...i'm concerned about the
interruption (for operational environment) on the underlying vpnv4 l3vpn.
Would be only momentary though right?... looks like 10 seconds from
"nbr_reset" to "Up"

If no way to avoid this, how do y'all do it ?  maint window?
