We are seeing “TTL expired in transit” with RC10 connected to a Cisco 12000.
Mikrotik wouldn’t connect to the Cisco with the MD5 key so we removed it.
After about 30 minutes of uptime, all BGP sessions restarted.
We are seeing over 10% packet loss between us and our upstream provider
after several minutes of uptime.
Downgrading back to 2.9.42 resolves the issue but still has the BGP “lockup
issue.”
