Point-to-point link dying while traffic is going across
<br />I have a point-to-point link between two sites. This link constantly has traffic going through it (it's a DR site), and we're replicating across the link. Sometimes (a lot this week), we "lose" connection to the other side. I've reported this to the provider, but they don't see anything in their switch.
<br />Tech specs of the link:
<br />L2 link across fiber connection to other site.
<br />Our router (3745) connects to the providers switch. The providers switch connects into the cloud, and this is mirrored on the other side: switch to a Cisco 2811. The providers switches are 2950s.
<br />I can get into the 3745 and ping the serial interface of the 2811 OR the LAN interface, and the link will come up. It seems like it's having to ARP for the address though because the first ping will timeout, but then it will start responding. I've replaced the cable on the other end, but haven't replaced the router. I don't have any mac addresses listed on the routers and the entry in the arp cache for that address exists. I've enabled tcp-keepalives-in and out on the main router (3745), but this hasn't helped.
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!
