CirrusF5 GTM link list question
Hello Teams,
I am a little bit confused about DNS -> GSLB -> Links -> Link List
I have reference to this KB (https://my.f5.com/manage/s/article/K6785) but still not very clear.
1. What is the purpose of this configure?
In KB, it said used to distinguish internal traffic and internet traffic. Is it a must to configure this?
And this is used to gather metrics from internet router?
2. In Router Address List, what IP should I used? The internet side self IP or gateway?
No, not required.
- 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."
- 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".
