 ipv6 address 2001:AAAA:BBBB:CCCC::1/64

router bgp XXXX
 bgp router-id 1.1.1.1
 bgp log-neighbor-changes
 no bgp default ipv4-unicast
 neighbor 2001:AAAA:BBBB:CCCC::2 remote-as 2
 neighbor 192.168.64.214 remote-as 2
 !
 address-family ipv4
  redistribute connected
  neighbor 192.168.64.214 activate
 exit-address-family
