Deactivation of the ipv6 address-family for an IPv6 BGP neighbor that is a member of a peer group may be removed when the configuration is reloaded or the system restarts.
BGP behavior may change after reboot
IPv6 BGP neighbors in a peer group Individual group members with different address-family configurations than the peer-group
If a neighbor must have different behavior than other peer group members it can be removed from the peer group and configured individually.
BGP address-family configuration is now correctly saved and reloaded for neighbors belonging to a peer-group.
