Achieving BGP ECMP with Check Point R80.30

HI Team,

I have 3 BGP Links terminated on 6900 firewall and I wanted to achieve BGP ECMP with link 1 and 3. I guess due to Path and certain BGP change its picking up best route. Can someone please help me editing BGP attributes so that I can achive BGP ECMP.

show bgp paths AS Path (AS Plain Notation): IGP.(Id-1) Nexthop: 0.0.0.0 LocalAS: 64520 NeighborAS: 0 Refs: 1 Ases: 0 Segments: 0 Overhead: 96 AS Path (AS Plain Notation): IGP.(Id-2) Nexthop: 0.0.0.0 LocalAS: 64520 NeighborAS: 0 Refs: 17 Ases: 0 Segments: 0 Overhead: 96 AS Path (AS Plain Notation): 1,IGP.(Id-23) Nexthop: 0.0.0.0 LocalAS: 64520 NeighborAS: 0 Refs: 1 Ases: 0 Segments: 1 Overhead: 102 AS Path (AS Plain Notation): (64520),65001,64520,IGP.(Id-61) Nexthop: 192.168.203.153 LocalAS: 64520 NeighborAS: 65001 Refs: 2 Ases: 2 Segments: 1 Overhead: 106 AS Path (AS Plain Notation): (64520),65001,IGP.(Id-62) Nexthop: 192.168.203.153 LocalAS: 64520 NeighborAS: 65001 Refs: 2 Ases: 1 Segments: 1 Overhead: 102 AS Path (AS Plain Notation): (64520),65520,4755,65520,IGP.(Id-63) Nexthop: 192.168.203.129 LocalAS: 64520 NeighborAS: 65520 Refs: 2 Ases: 3 Segments: 1 Overhead: 110 AS Path (AS Plain Notation): (64520),9730,Incomplete.(Id-64) Nexthop: 172.43.149.41 LocalAS: 64520 NeighborAS: 9730 Refs: 10 Ases: 1 Segments: 1 Overhead: 102 AS Path (AS Plain Notation): (64520),9730,9730,IGP.(Id-65) Nexthop: 172.43.149.41 LocalAS: 64520 NeighborAS: 9730 Refs: 2 Ases: 2 Segments: 1 Overhead: 106 AS Path (AS Plain Notation): (64520),9730,9730,9730,9730,9730,IGP.(Id-66) Nexthop: 172.43.149.41 LocalAS: 64520 NeighborAS: 9730 Refs: 4 Ases: 5 Segments: 1 Overhead: 118

I would suggest to contact CP TAC for this...

Do you have a diagram to accompany the above?

The following SKs will help with the fundamentals of ECMP & AS_PATH prepending which are likely required here:

sk100504 (ECMP)

sk103047 (AS_PATH)

That said it's probably more something for Pro Services than TAC.
