Hello

We run multiple VyOS routers for edge peering and have upgraded one of our routers to the following version:

2025.04.01-0021-rolling

I've found that under the hood FRR enforces a configuration for BGP peers that affects prefix ingestion if that peer is a route-server. This is related to enforce-first-as configuration parameter which seems to be a default as prefixes from the route-servers don't append their AS in the AS_PATH.

VyOS doesn't seem to have syntax functionality to solve this default behavior. This requires me to go into FRR shell and run the appropriate commands to fix this:

conf t
    router bgp {ASN}
    no neighbor {BGP-PEER} enforce-first-as

Please could you look at fixing for future releases by providing a configuration command to disable "enforce-first-as". As this configuration is currently done in FRR shell directly, after reloading the router that configuration is lost and needs to be manually applied again, which isn't ideal.
