Hi,
I have been setting up a small network, at the moment there is 4 edgerouter pro's running OSPF with one eBGP peer with full routes, there are more peers to be added shortly.
If I run firmware <= 1.7.0 then performance is great and there is no issues
On firmware >=1.8.0:
(1) iBGP seems to take 10 minutes to sync routes (although no actual traffic on network).
(2) The output of show ip bgp summary is laggy
(3) The CPU seems to average >50% instead of ~5% on 1.7.0
A snapshot of the problem:

Masked BGP config:

And of course the BGP summary:

IP's and ASN is blanked.
I have tested loading different system images and its consistently failing with >= 1.8.0
I can't find a clear answer on these forums to what may be causing this, I notice a big change is the binary /usr/sbin/ribd is newly introduced. I assume it replaces something else?
As this is still in development, I can play with the setup for now, but its heading to live status shortly and don't really want to be stuck on outdated firmware.
Any help please
