MPLS L3VPN Load Balance on
Smartgroup Link
In current network, services require more and more bandwidth.
A common situation is that a gigabit or 10–gigabit link can not
meet the requirement of services. In this situation, ECMP and
aggregation of multiple links can solve the problem in Layer 3.
Aggregation of multiple physical links can solve the problem in
Layer 2.
MPLS/VPN function is used widely in internal metropolitan core
networks and enterprise networks. In MPLS/VPN network, load
balance on Smartgroup link has important function. Smartgroup
link may exist between CE and PE, PE and PE, PE and P, P and P.
ZXR10 8900 series switch supports MPLS L3VPN load balance on
Smartgroup link. Moreover, ZXR10 8900 series switch supports
different load balance policies in different situations.
ZXR10 8900 series switch can implement load balance on Smart-
group link composed of GE, 10–GE and FE in the following modes.
