I need some help with VyOS and some weird issue that I have stumbled upon. I have two instances, which are running BGP. Both instances have other BGP peers and they work fine. They receive hundreds of thousands of prefixes without a problem. However, when I try to make them peer together (either via iBGP or via BGP confederations), one of the two (at random), in “show ip bgp summary” starts receiving prefixes, and by running the command multiple times, I can see them go up… 100k, 200k, 300k, … However, when they reach the full 700k-something of the IPv4 table, the connection state moves to “Clearing”, and then “Idle”, and then all over again…
CPU usage is at 50% all the time this happens, and prefixes are transferred between the two routers all the time.
Both routers have “soft-reconfigure inbound” in their “neighbor” block and “remote-as”, and that’s it.
It happens both using iBGP (same private AS, same confederation “peer-id”), as well as CFBGP (different private AS, same confederation “peer-id”, added as “peers”).
Any idea what might be causing this?
