Hi,
I use a RB1200 with v5.13 and I have a couple of /24’s routed over a /30.
The following strange thing happens, at first my ISP and I setup the /30.
When I ping from the RB the router of my ISP I get: sent=300 received=300 packet-loss=0% min-rtt=2ms avg-rtt=8ms max-rtt=15ms.
Then my ISP route the /24’s to me. From that moment on my ping to the router of my ISP changes into: sent=300 received=300 packet-loss=0% min-rtt=5ms avg-rtt=14ms max-rtt=28ms. At that time there is no heavy traffic, just 2 Mbit on a 100Mbit line.
As you can see my avg ping is 9ms higher. This higher ping also occurs when I ping beyond the router of my ISP. The overall ping is less stable and it moves more up and down. So far we can not find the problem, neither on the ISP side as on my router. This same setup has worked before without a problem. Have to say that the RB then had an older OS version installed (can’t remember exactly which version).
Anybody an idea what is going wrong here?
Thx
