## VCN routing thru DRG is dependent on some factors:
## 1) If there's a Hub VCN (3 or 4), the route to DRG is always enabled, because the Firewall in the Hub VCN will constrain traffic appropriately.
## 2) If there's no Hub VCN (1 or 2), the route to DRG is enabled by default or if explicitly configured via the 'tt_vcn1_routable_vcns' attribute.
## Explicitly setting 'tt_vcn1_routable_vcns' constrains routing to provided VCNs only.
