[c-nsp] next-hop-self under address-family vpnv4 also?

[CiscoNSP List]

Is it recommended to add it under vpnv4 also?

i.e.

router bgp xxxxxx
...
neighbor iBGP-IPv4-PEERS update-source Loopback0
neighbor iBGP-IPv4-PEERS next-hop-self
neighbor xxx.xxx.xxx.xxx peer-group  iBGP-IPv4-PEERS...
address-family vpnv4
  bgp redistribute-internal
  neighbor  iBGP-IPv4-PEERS send-community extended
  neighbor iBGP-IPv4-PEERS next-hop-self
  neighbor xxx.xxx.xxx.xxx activate

Cheers.
