I found abnormal behavior during label allocation. As I wrote above VyOS generate label for all prefixes presented in routing table. But when we have for example 5 connected routes (four /24 and one /32) on Egress LSR and we start mpls VyOS allocates labels for all routes and neighbor (downstream LSR) receives label=3 (implicit null). But if we have 2 connected routes (one /24 and one /32) then we start mpls, Egress LSR allocates labels for all routes (two in this case), but if we add on Egress LSR one, two or more new connected routes VyOS does not allocate label=3 for this routes and does not send Label Mapping Message to its neighbors for FECs related to new added routes. The software version is 1.3-rolling-202005160117

Hi, everyone.
As I understood from my lab VyOS generate label in cisco fashion (for all presented prefixes in routing table). And it is good as for me. But I think it is necessary to be able to filter the FEC for which labels will be generated (for example only for /32 routes, or only for particular routes).
