Hi,
I have two uplinks (different AS), and one is more stable/preferred, but when "merge paths" is set to on, all routes are generated with weight 1:
5.21.41.0/24 proto bird nexthop via 10.16.0.1 dev uplink1 weight 1 nexthop via 10.17.0.1 dev uplink2 weight 1
Is there any way to adjust weight for ECMP generated from BGP sessions?
I could not find any option/attribute when it is related to BGP or kernel protocol, while it is possible for OSPF and static protocols (to a degree).
Adjusting local preference or med (in BGP) does not really help - weight is unchanged, though of course I could force routes from specific AS to be preferred, but then I lose ECMP and if preferred session is dropped it takes time to restore connectivity.
Thank you!
I'd just like to say I'm very interested in this aswell, it would be an amazing feature to have. -N
