Implementing Auto VPN Tenant Isolation

Implementing Auto VPN Tenant Isolation

Service Description

When a carrier provides services for tenants, the tenants need to be isolated to allow data transmission between specific tenants.

Figure 1-5  Auto VPN tenant isolation

Networking Description

On the network shown in Figure 1-5, CE1 and CE2 belong to a tenant, and CE3 and CE4 belong to another tenant. The following requirement needs to be met:
  • CE1 and CE2 can communicate with each other.
  • CE3 and CE4 can communicate with each other.
  • CE1 and CE3 are isolated from each other.
  • CE2 and CE4 are isolated from each other.

To meet this requirement, the RR must reflect only a local tenant's routes and isolates routes from the other tenants. Specifically, the following configurations need to be performed on the RR:

  • Add PE1 and PE2 to the peer group Group1, and add PE3 and PE4 to the peer group Group2.
  • Configure the import route-policy Group1_in and export route policy-Group1_out for Group1.
  • Configure the Group1_in policy to apply the community attribute aa1:nn1.
  • Configure the Group1_out policy to filter routes based on the community attribute aa1:nn1.
  • Configure the import route-policy Group2_in and export route-policy Group2_out for Group2.
  • Configure Group2_in to apply the community attribute aa2:nn2.
  • Configure Group2_out to apply the filtering community attribute aa2:nn2.

The route policies configured allow the RR to reflect routes only from the same tenant. In this manner, services can be transmitted between CEs of the same tenant, and services of different tenants can be isolated.
