Need help for configuring - Traffic Control CDN
Hi, We have plan to use Apache Traffic Control for our CDN. But we are struggling in configuring traffic control. Currently we are using Traffic Control version 3.xx. 1) We need a detailed information about Traffic Router module. In your docs its telling CR as DNS Auth, here we are confusing whether T-Route has its own DNS server as in-built or we have to configure the one like BIND ? 2) In Traffic Ops, postinstall script asking for cdn domain name, so we have configured like "cdn.mydomain.com" for traffic router and provided it to Traffic Ops. Is it the correct way of doing this ? 3) trafficops.properties in T-Route its just asking for user name and password for traffic ops user, we configured it even-though T-Router log was shows us like "No traffic ops hostname yet!". Traffic Router Log ============== [root@cdn ~]# tail -f /opt/traffic_router/var/log/traffic_router.log ERROR 2018-10-27T17:10:43.805 [pool-2-thread-1] com.comcast.cdn.traffic_control.traffic_router.core.secure.CertificatesClient - No traffic ops hostname yet!

Kindly help us in the process of configuring traffic control. Thanks & Regards, Sridhar Ananthakrishnan

Hello,
If you are still working on this... The "peers.polling.interval" must be
configured in Traffic Portal under parameters.
Name: peers.polling.interval
Config File: rascal-config.txt
Value: 5000
Secure: false
