• IES and VPRN Layer 3 spoke-SDP terminated interfaces
• Epipe services with spoke SDPs
• Ipipe services with spoke SDPs
• VPLS services with spoke or mesh SDPs
• VPRN OSPF PE-CE interfaces
The weight of the LSP is configured using the config>router>mpls>lsp>load-
balancing-weight weight and config>router>mpls>lsp-template>load-
balancing-weight weight commands.
3.13.1 Weighted ECMP for VPRN Services with Auto-bind
Weighted ECMP for VPRN services with auto-bind is enabled using the
config>service>vprn>auto-bind-tunnel>weighted-ecmp command. This
command is applicable if the auto-bind tunnel is configured for RSVP or SR-TE using
the config>service>vprn>auto-bind-tunnel>resolution-filter>rsvp/sr-te
command.
If weighted ECMP is enabled, a path is selected based on the output of the
configured hashing algorithm. Packet paths are then mapped to LSPs for the service
in proportion to the configured load-balancing weight of the LSP. The hash is based
on the system load-balancing configuration. Weighted ECMP is disabled by default.
If an LSP in the ECMP set has no load-balancing weight configured, and the ECMP
is set to a specific next hop, regular ECMP spraying is used.
3.13.2 Weighted ECMP for EVPN
ECMP for Layer 2 unicast traffic on Epipe and VPLS services for EVPN-MPLS
destinations is enabled using the config>service>epipe>bgp-evpn>mpls>auto-
bind-tunnel>ecmp command or config>service>vpls>bgp-evpn>mpls>auto-
bind-tunnel>ecmp command. These commands allow the resolution of an EVPN-
MPLS next hop to a group of ECMP tunnels of type RSVP-TE or SR-TE.
Note: SR-TE LSP templates are currently not supported.
