[c-nsp] 6vpe - me3600x

[Adam Vitkovsky]

I should have mentioned that this has some serious implications to it
especially in large BGP environments
So please consider the number of TCP sessions you'll end up with on RRs as
well as on PEs

I thought this is on by default but apparently it's not

Try
neighbor x.x.x.x transport multi-session

(resending due to ugly formatting)

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?
