Does NE40/80 support BGP iteration load balance?
NE40/80 supports BGP iteration load balance from VRP3.10-0426sp01 version.
Between two routers realize link backup by setting up many links. If links are normal, load balance of the traffic can be realized.
Between two routers set up BGP neighbor through loopback interface, the next-hop is BGP peer. BGP sets up loopback interface address. The BGP route iterates the route of loopback interface address and is valid. The BGP route had only one next-hop. BGP iterates load balance make BGP route map many next-hop of IGP route and realize load balance of the traffic.
NE40/8 can support load balance of three links at most.
Details can be seen in attachment.
At route table iterated BGP route has only one next-hop and egress. Check FIB table and this BGP route can iterate three next-hop and egress.
