Configuring Service Device Pools for Load Balancing PPPoE and LNS Subscribers
With dynamic L2TP network server (LNS) configuration,
you can replace the services-interfaces with a service-device-pool in the tunnel-group
for load balancing LNS subscribers. Optionally, you can use the service-device-pool statement for load balancing to
dynamically select the inline services (si) interface for both bundle (PPPoE or LNS subscribers), and LNS member
link, respectively.
The service-device-pool configuration
enables interface overlap, which can result in over usage of the overlapped
interfaces.
Before you begin, enable the inline service interfaces for all FPC slots and PICs. See Enabling Inline Service Interfaces for PPPoE and LNS Subscribers.
The following example shows how to configure two service device pools (pool1 and pool2) for inline services for load balancing bundle and LNS member link.
To configure two service device pools:
The following shows sample output when all referenced FPC slots and PICs had been enabled for inline services:
services {
service-device-pools {
pool pool1 {
interface si-1/0/0;
interface si-1/1/0;
interface si-3/0/0;
}
pool pool2 {
interface si-1/1/0;
interface si-2/1/0;
interface si-5/1/0;
}
}
}
