Hi,
I remember seeing this issue in FRR v9 but thought its covered in VYOS.
Thanks

running version
VyOS 1.5-rolling-202403010026
are you using LDP or BGP LU to the label distribution ? I don’t see any significant bug in FRR/9.1 that is current version that we use. Could you share your configuration ?

LDP + MPBGP
This is VRF config, rest of VRFs are exactly same config
set vrf name VRF9963 protocols bgp address-family ipv4-unicast export vpn
set vrf name VRF9963 protocols bgp address-family ipv4-unicast import vpn
set vrf name VRF9963 protocols bgp address-family ipv4-unicast label vpn export 'auto'
set vrf name VRF9963 protocols bgp address-family ipv4-unicast rd vpn export '172.27.1.1:211'
set vrf name VRF9963 protocols bgp address-family ipv4-unicast route-target vpn both '56565:211'
set vrf name VRF9963 protocols bgp parameters router-id '100.100.100.1'
set vrf name VRF9963 protocols bgp system-as '65501'
set vrf name VRF9963 table '9963'
Here you can see MPLS table output, BGP label pool is 80-207

I haven’t found any interested information about that you mentioned , open a case with FRR in GitHub if there is any limitation or a way to expand the label location to bgp.

Thanks Fernando for checking. I cut this with FRR Limited number of VRFs in VPNv4 · Issue #16744 · FRRouting/frr · GitHub and following up there.

thanks for sharing, yes, looks like a bug with the bgp labels range.
