Hi

IPv4 ECMP for OSPF and static routes is supported since long ago.

IPv4 ECMP for RIP is supported since v1.5.0.

IPv4 BGP multipath is supported in master branch in devel tree
(commit 8d9eef17713a9b38cd42bd59c4ce76c3ef6c2fc2).

IPv6 ECMP is currently not supported. There also may be problems in
kernel multipath forwarding unrelated to BIRD (as mentioned by d tbsky).
