Hello,
I got this:
Well, both B1-Distribution-1 and B1-Distribution-2 announce
192.168.0.0/24 since one is 192.168.0.2/24 and the other is 192.168.0.3/24 (planning to do VRRP here later).From my understanding B1-Core should get two LSPs (one from each neighbor) and both of those should have
192.168.0.0/24, so B1-Core should use ECMP to reach the 192.168.0.0/24 subnet. What am I missing, because that's not working.
B1-Core:
