BGP peering is supported for IPv6 in the VMware no access, VMware write access, VMware read access, Linux server, and bare-metal cloud ecosystems.

Configuring IPv6 BGP Peer

Note:

Similar to an IPv4 BGP peer, the IPv6 peer must be in the Service Engine’s directly-connected network. If it is an eBGP multihop peer, then you need to configure the IPv6 subnet of the Service Engine’s interface as subnet6, through which the multihop peer is reachable.
