Good day all,
I am very new to this communtiy and am really hoping to get some help with the problem I am facing in load balancing our ISP outgoing traffic.
We have an M10i with 4 equal cost STM-1 routes to our service provider, Namibia Telecom. Incoming traffic is load balancing very nicely ,but for some reason I am not sure of, BGP selects only one path for outbound traffic. (Attached is the router config- attention is on BGP group NAMIBIA TELECOM)
zamtel@ZMT-ZM-LMY-PR-001> show route 0.0.0.0
inet.0: 6017 destinations, 6507 routes (3445 active, 0 holddown, 2584 hidden)
+ = Active Route, - = Last Active, * = Both
0.0.0.0/0 *[BGP/170] 1d 07:34:26, localpref 100, from 41.205.152.182
AS path: 20459 I
> to 41.205.146.61 via so-0/1/0.0
to 41.205.146.65 via so-0/1/1.0
to 41.205.146.49 via so-1/0/0.0
to 41.205.146.57 via so-1/0/1.0
The current BGP config uses multihop with static routes to our peers loopback address. Attempts to use 'multipath', 'load balancing per-packet' and applying the outbound policy in the forwarding table have failed. I still get outbound traffic going through one interface.
Kindly have a look at the config attached and please advise where I am going wrong.
I would be extremely grateful for any assistance/advice.
