Severity: 3-Major


when a neighbor with ipv4 address is disabled in ipv6 address family, show running configuration displays that the neighbor is disabled. However, when we restart or reboot the tmrouted or bgp protocol, the neighbor is enabled again. The configuration persistence is not maintained.


configuration persistence is not maintained. This impacts the BIGIP upgrades as the configuration loaded is not the same as it was before the upgrade. Similarly, a restart/reboot will also have different configuration loaded than originally used. This might alter the intended behavior of the protocol that the use expects to function.


1. disable a neighbor with ipv4 address in ipv6 address family. 2. reboot/restart tmrouted or bgp protocol


disable the neighbor again.

Fix Information

configuration persistence is maintained for the disabled neighbor with ipv4 address in the ipv6 address family.
