Configuring VPN Aggregation
VPN aggregation configurations have the following requirements.
All interfaces in a pool must belong to the same service
PIC.
Logical interfaces cannot be in more than one pool.
All interfaces must have either family inet or family inet6 configured.
Logical unit 0 cannot be configured in a service interface
pool.
The maximum number of service interfaces in a pool is
1000.
The service set must have a next-hop service that is set
to the service interface pool; it cannot have inside and outside services.
The service set must have a BGF rule.
In the virtual interface configuration, the service interface
must match the interface configured in the VRF routing instance.
The virtual interface configuration must include all media
services in the BGF rule that is configured in the service set.
Step-by-Step Procedure
See Figure 23 for an illustration of this configuration.
To configure VPN Aggregation:
Configure a policy statement to be used for
the vrf-import and vrf-export policies that you plan to configure
in the routing instances.

user@host#edit policy-options policy-statement

[edit policy-options policy-statement policy-1]
user@host#set term t1 then reject
Configure a VRF routing instance for
each VPN.

user@host#set route-distinguisher 10.10.10.33:0
user@host#set vrf-import policy-1
user@host#set vrf-export policy-1
Configure a pool of logical service interfaces
that are configured in the VRF routing instances.
[edit]
user@host#edit services service-interface-pools

[edit services service-interface-pools pool vrf-pool]
user@host#set interface sp-1/0/0.10
user@host#set interface sp-2/0/0.10
user@host#set interface sp-3/0/0.10
Create a service set that links the VRF
and the BGF services. Specify the service interface pool as the next-hop
service. The service set must contain a BGF rule. It cannot contain
any other type of rule.

Configure a virtual interface for each
VRF routing instance.
