The confederation route unicast-to-label disable command prevents non-RRs from advertising the IPv6 non-labeled routes learned from peers in the local confederation as labeled routes carrying a label of all Fs to the BGP peers in another confederation.
The undo confederation route unicast-to-label disable command restores the default configuration.
By default, non-RRs can advertise the IPv6 non-labeled routes learned from peers in the local confederation as labeled routes carrying a label of all Fs to the BGP peers in another confederation.

confederation route unicast-to-label disable
undo confederation route unicast-to-label disable
If two PEs that are not RRs reside in two confederations, the PEs can advertise labeled routes carrying a label of all Fs to each other by default. However, non-Huawei devices may consider the label of all Fs invalid, and if these non-Huawei devices receive such labeled routes, BGP peer relationships may be disconnected. To prevent this problem, run the confederation route unicast-to-label disable command to prevent the PEs from advertising labeled routes carrying a label of all Fs.
