Build 2 MPLS LSPs to the destination router, turn on OSPF on those
shortcuts, and use ECMP. JunOS will see them as 2 completely identical
paths to the end-device, and load-balance across them.
Enable ECMP load balancing:
routing-options {
forwarding-table {
export load-balancing-policy;
}
}
policy-options {
policy-statement load-balancing-policy {
then {
load-balance per-packet;
}
}
Note that "load-balancing per-packet" is a misnomer, and a holdover back
to the Internet Processor #1 on the original M40/M20. We actually do
per-flow load balancing when this is enabled; so as not to upset the
path/timings/order of things like VoIP RTP packets.
