Description:
- Allows another network to communicate thru private IP addresses
| Dedicated (direct to Google) | Shared (thru ISP/partner) | |
|---|---|---|
| Layer 3 (Peering over Public IP) | GCP Network Peering | GCP Carrier Peering, GCP Partner Interconnect |
| Layer 2 (Direct access with internal IP) | GCP Dedicated Interconnect | GCP Partner Interconnect |
| Over Internet | GCP Virtual Private Cloud & HA VPN | Public IP |
- Cross-cloud Interconnect
- Layer 3 meaning rent office in Google Pop
- Interconnects are different from peering in that they give you connectivity using private address space into your Google VPC
- Layer 2 is thru Internet Service Provider
1. Network connectity center:
2. GCP Virtual Private Network and High Availability Virtual Private Network
3. Interconnect:
- Connect in very high-volumn data
- VLAN attachment:
- Connections between your local routers and Google Cloud routers for your Dedicated or Partner Interconnect connections.
- Physical connection:
- Establish high bandwidth, low latency connections between your Google Cloud VPC networks and your on-premises infrastructure.
- Interconnect type:
- Typical IPsec VPN protocol:
- Go through public internet, encypted
- Requires On-premises VPN gateway
- GCP Dedicated Interconnect
- GCP Partner Interconnect
-
Cross-cloud:
- Typical IPsec VPN protocol:
4. Cloud routers:
- GCP Router
- Let other networks and GCP Virtual Private Cloud exchange route information over the VPN using the Border Gateway Protocol
- Using this method, if you add a new subnet to your Google VPC, your on-premises network will automatically get routes to it.
