Hi Daniil,

Thanks for the prompt reply.

If they co-exist , can they exist in one BGP instance or do we need to have two separate instances?

Precisely is the below configuration valid or any further changes required :-

router bgp 7675
 bgp router-id 1.1.1.10
 neighbor 1.1.1.1.20 remote-as 7675
 neighbor 2001:468:555:200::6 remote-as 7675
 network 5.0.0.0/8


address-family ipv6 unicast
 no bgp default ipv4-unicast
 neighbor 2001:468:555:200::6 activate
 network 2001:468:4ff::/48
exit-address-family 

Thanks
Chaitanya

Hi Chaitanya,
They indeed may co-exist and it's a common practice. You may want to
    add "no bgp default ipv4-unicast" to prevent your IPv6 neighbors
    from advertising IPv4 unicast capability if you know or suppose your
    IPv6-only peers may not like it.
