Hello Support,
I've seen many examples of the DNS SRV records and have read the VCS Cluster Creation Deployment Guide for X8.1 example. I was hoping I could a second set of eyes to verify that my DNS configuration below is accurate. Here is what I have so far:
VCS Expressway LAN 1 Ports are to be used for the VCS Cluster in the DMZ and will not be NAT'd. LAN 2 Ports point to the public internet and are NAT'd.
- Domain: vc.example.com
- Cluster A Record: vcse-nb.vc.example.com points to both VCS Expressway IP address in Round Robin fashion with equal weight and priority (12.x.x.1 and 12.x.x.2)
- VCS Expressway A Records
Vcse-nb-1.vc.example.com – 12.x.x.1
Vcse-nb-2.vc.example.com – 12.x.x.2
DNS SRV Records
_sips._tcp.vc.example.com. 86400 IN SRV 1 1 5061 vcse-nb-1.vc.example.com.
_sips._tcp.vc.example.com. 86400 IN SRV 1 1 5061 vcse-nb-2.vc.example.com.
_sip._tcp.vc.example.com. 86400 IN SRV 1 1 5060 vcse-nb-1.vc.example.com.
_sip._tcp.vc.example.com. 86400 IN SRV 1 1 5060 vcse-nb-2.vc.example.com.
_h323ls._udp.vc.example.com. 86400 IN SRV 1 1 1719 vcse-nb-1.vc.example.com.
_h323ls._udp.vc.example.com. 86400 IN SRV 1 1 1719 vcse-nb-2.vc.example.com.
_h323cs._tcp.vc.example.com. 86400 IN SRV 1 1 1720 vcse-nb-1.vc.example.com.
_h323cs._tcp.vc.example.com. 86400 IN SRV 1 1 1720 vcse-nb-2.vc.example.com.
My question is in this example would I need to create SRV records that point to the Cluster A record? I have seen many examples of this but I can't seem to wrap my head around why this would be needed. I appreciate you help!
Thanks,
Joe
