Abnormal delay in pinging the gateway ip through WAN 2.5G port.

Hello FURRYe38 

So the R7000 exhibits the same problem when connected to the ISP gateway? 

no, There is no ping ISP gateway latency when the R7000 is connected to an ISP gateway.

 

Are you using the ISP gateways DMZ or IP-pass thru for the SXR router? 

All I can say is that whether the SXR80 is connected to the ISP gateway or the R7000, the WAN gets the ip address directly from their DHCP.

If the ISP gateway is in router mode, you should be using it's DMZ or IP pass thru for any external router connected to it. 

 

So if you select 1Gb on the SXR for the WAN connection, no abnormal delay is seen with the SXR connected to the ISP Gateway? 

yes, I have tried to set the WAN of the SXR80 to the port2(1G) interface, no ping ISP gateway latency issues.

 

 

When I connect according to this topology diagram, I also get abnormal delays, so this shouldn't be a problem with the ISP gateway or LAN cable, and I purchased this R7000 in July 2014

Since the connection with the R7000 if you have this in the mix between the ISP router and SXR, you probably should use the 1Gb WAN port connection since the R7000 only has 1Gb WAN/LAN ports. 

 

Something to check with NG about and see if they can help with this. Again, the 80 series is EoL so not sure if there would be any more FW updates to resolve this and the 2.5Gb WAN speed issue. Something to ask them about.
