Hi @eBPFCilium,

VyOS 1.1.8 is EOL - however if you find this CLI node: set protocols bgp <ASN> maximum-paths it will support ECMP. Unfortunately I no longer have such an old version running to verify this.

You should upgrade to at least to VyOS 1.2.8 or even better, use the equuleus 1.3 release (currently 1.3.1)

Thanks c-po.
vyos@R1# set protocols bgp 65005 maximum-paths ebgp 2
but it seems not working.

From this isseu:

We can see that: we need config the

But if even with the 1.2.1:

we can not get the:multipath-relax
set protocols bgp ASN parameters bestpath as-path multipath-relax

Without AS path multipath relax ECMP will only work on “same” paths.

You can try this in FRR itself:

vyos@vyos:~$ vtysh
vyos# configure
vyos(config)# router bgp 100
vyos(config-router)# bgp bestpath as-path multipath-relax

NOTE: this will be a workaround only and be lost on the next reboot. Please upgrade your VyOS version.
