    No, not required.

    1. From the manual: "A link is a logical representation of a physical device (router) that connects your network to the Internet. BIG-IP Global Traffic Manager (GTM) tracks the performance of links, which influence the availability of pools, data centers, wide IPs, and distributed applications."
    2. The IP should be the local IP from your router on the connection to your ISP. So for example, if your ISP connection is a /31 and the remote ISP router IP is 10.0.0.0/31 and your local router IP in that ISP subnet is 10.0.0.1/31, then the address you'd use is 10.0.0.1.

For anyone configuring a GTM Link, its status is dependent on a GTM Server, so make sure you have that configured and monitored and is up.

BTW the Link health monitor monitors the links in the "Router Address List" not the "uplink".
