LoadBalancing/Policy Routing BGP Dual-Homing

RouterOS Forwarding Protocols
1

Hello Everyone,

I am implementing dual-homing with a Mikrotik router on the customer site. The two routers of the ISP are Cisco. Mikrotik will only receive default route from the two.

I have read this subject on Cisco:
https://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/13762-40.html

Since I know Mikrotik does not support ECMP BGP. And RouterOS installs all the same prefixes from eBGP into RIB. So can we configure Loadbalancing/Policy routing by PCC/Mangle routing
for it? Any concerns about this solution? It works with my labs but I am not sure if it would be fine in fact.

Please correct me if I am wrong about something.

Thanks

Hi, I need to know the same, how to configure the routing filter to take the prefixes in ecmp via bgp.

My filter at the moment is:

if (bgp-communities equal 99:99) {set gw 10.255.241.97;accept}

but i need it to be ecmp with ip 10.15.18.20

I have not found a manual for the very specific routing filter options.
