CGR 1020 - Interface Issue

[himanshudwivedi]

Hello Team,

I have configured CGR 1120 Router with 2 ISP I am able to Successfully Ping both  the Neighbor IP Address from My Router. But after sometime I am unable to Ping the both  the  IP Address at the same time. I have checked all the configuration seems to be OK. When I reboot the router both IP both the link works fine, but after sometime again goes down. Can any one suggest and help me out in this case. 

Note : Both the links remains stable on other vendor router.

interfaces are G2/1 and G2/2

Hello,

the 'half-duplex' looks suspicious. Check if the ISP setting is full duplex, and make sure both sides actually are:

GigabitEthernet2/2 is up, line protocol is up
Hardware is Gigabit Ethernet, address is f80f.6f80.3d62 (bia f80f.6f80.3d62)
Description: ### CONNECTED TO AIRTEL- LINK ###
Internet address is 150.150.167.33/30

Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
--> Half Duplex, 100Mbps, media type is RJ45

When It was down, I visited and tried it by Changing All Duplex and Speed for both the ISP but then too it was not pinging. Actually I have assigned Auto Duplex sonit automatically getting the duplez setting from ISP. The main thing is that both the ISP are unreachable at same time.
