Parameters
ldp — Specifies LDP to be the automatic binding for the SDP assigned to the service.
gre — Specifies GRE to be the automatic binding for the SDP assigned to the service.
autonomous-system
Syntax autonomous-system as-number
no autonomous-system
Context config>service>vprn
Description
This command defines the autonomous system (AS) to be used by this VPN routing/forwarding
(VRF).
The no form of the command removes the defined AS from this VPRN context.
Default
no autonomous-system
Parameters

ecmp
Syntax ecmp max-ecmp-routes
no ecmp
Context config>service>vprn
Description
This command enables equal-cost multipath (ECMP) and configures the number of routes for path
sharing. For example, the value of 2 means that 2 equal cost routes will be used for cost sharing.
ECMP groups form when the system routes to the same destination with equal cost values. Routing
table entries can be entered manually (as static routes), or they can be formed when neighbors are
discovered and routing table informationis exchanged by routing protocols. The system can balance
traffic across the groups with equal costs.
ECMP can only be used for routes learned with the same preference and same protocol. See the
discussion on preferences in the static-route command.
When more ECMP routes are available at the best preference than configured by the max-ecmp-
routes parameter, then the lowest next-hop IP address algorithm is used to select the number of routes
configured.
