Im a bit confused on what TLOC color we should be using for certain connections. I know the color selection will hint to the remote device wether or not it should use its NATD public IP for data plane connection but in my current environment we have a mix of DIA only sites and MPLS only sites. So for example:
Site A has 1 MPLS circuit and Site B has a DIA circuit. In order for site A to talk to site B , it needs to traverse a NAT/PAT device in my Data Center. According to Cisco, if a device sites behind a NAT device , give it a public color so that it uses my nat public ip to form ipsec. Cool but if i did that , how would site A talk to another MPLS site? Theres no nat inbetween them .
Going through the documentation i cant find any info on this scenario.
