The Juniper default is to not do ECMP at all. Only a single route is
programmed into the FIB for each prefix in your RIB. If you e.g. have
routes to 198.51.100.0/24 pointing to ten different ports, all traffic
to that entire /24 will go out over a single port, unless you have
explicitly enabled ECMP.
To enable ECMP, you need this:
policy-options {
policy-statement ecmp {
then {
load-balance per-packet;
}
}
}
routing-options {
forwarding-table {
export ecmp;
}
}
in your configuration. Note also that "per-packet" is a mis-nomer; it
is really "per flow", based on a hash of the L3/L4 headers.
'show route forwarding-table destination 198.51.100.0/24' shows if you
actually have multiple routes in your FIB.
