[j-nsp] IPv6 BGP support on EX-series

Hi.

I was considering Juniper EX-4200 with AFL to an IPv4+IPv6 BGP
scenario where the number of FIB routes is enough, but this part of
the specs(http://www.juniper.net/us/en/local/pdf/datasheets/1000215-en.pdf)
is worrying me:

Layer 3 Features: IPv4
• Max number of ARP entries: 16,000
• Max number of IPv4 unicast routes in hardware: 10,000
• Max number of IPv4 multicast routes in hardware: 2,000
• Routing protocols: RIPv1/v2, OSPF, BGP, IS-IS
• Static routing
• Routing policy
• Bidirectional Forwarding Detection
• Layer 3 redundancy: VRRP
Layer 3 Features: IPv6
• Max number of Neighbor Discovery (ND) entries: 16,000 (shared with IPv4)
• Max number of IPv6 unicast routes in hardware: 1,000
• Routing protocols: RIPng, OSPFv3
• Static routing

Would that mean that there is no BGP IPv6 support ? Wouldn't that
contradict with the supported RFCs section ?

RFC 2283 Multiprotocol Extensions for BGP-4
RFC 2545 Use of BGP-4 Multiprotocol Extensions for IPv6 Inter-Domain Routing

I can especulate that there is no support for IPv6 BGP neighbors but
there is support for IPv6 address-family in IPv4 BGP sessions, is that
so ?

(As for JunOS version goes, it seems it would run 9.5R4 for starters)
