I have a question with ECMP: i would like to know if it's possible or what alternatives there are to do load balancing in this tophology with OSPF or another IGP:
Code: Select all
R1 --------> Sw1 --------> |
| | R2
|__________> |
R1 = CCR2004 (router with OSPF)
Sw1 = CRS317 (switch)
R2 = RB4011 (router with OSPF)
Sw1 ->R1 they are 2 wireless links
Code: Select all
R1 SIDE:

Any help would be appeciated!
