Info
titleNOTE:
  • Enable IP routing function before using this feature, for details please refer to Configuring IP Routing.
  • The static route that specifies the next hop address and the one that specifies the outgoing interface are not considered for ECMP load sharing, even if they have equal cost.

In L2/L3, all routing entries will be configured to the ASIC switching chip if the outgoing VLAN-interface is link-up, and the outgoing physical port is learning.

With the show route forward-routeipv4 all command, all the route entries in the ASIC chip will be displayed. Following the show route table ipv4 unicastfinal command, all routes in the RIB of the kernel will be displayed.

 

Configure max-route-limit.

Before configuring max-route-limit, check the forward-route table:

Note: The switch supports 12k ipv4 routes at most and 6k ipv6 routes at most. One ipv6 route is equal to two ipv4 routes. The directly-connected routes are not excepted to route limit.
