Hello Everyone,
I have configured 2 Routers with 4 parallel links. Each router has a loopback address. I have advertised loopback addresses of the loopbacks in EIGRP. The FD is equal on all the links. I see 4 paths in the routing table of each router for a given loopback address. According to my understanding there should be load balancing between all the 4 links. But I see load balancing between only 2 links. All 4 are not participating in the load balancing.
I have captured the packets on all the 4 links. I see packets are transferred through only 2 links. I am using ping to send the traffic.
Configuration on R1:
router eigrp 1
maximum-paths 6
network 1.1.1.1 0.0.0.0
network 100.10.10.0 0.0.0.255
network 100.10.20.0 0.0.0.255
network 100.20.10.0 0.0.0.255
network 100.100.100.0 0.0.0.255
Configuration on R2.
router eigrp 1
maximum-paths 6
network 2.2.2.2 0.0.0.0
network 100.10.10.0 0.0.0.255
network 100.10.20.0 0.0.0.255
network 100.20.10.0 0.0.0.255
network 100.100.100.0 0.0.0.255
Thanks,
