Usage
guideline
This command supports two operation modes: WCMP load balancing mode and non-WCMP load
balancing mode. In the former mode, the system implements WCMP load balancing according to the
weight inputted.
Up to 32 IP addresses may follow the set ip default next-hop command.
If a weight follows ip address, up to 4 next hop IP addresses can be configured.
Note: If a weight follows any next-hop, the operation mode of this command will be automatically
switched to the WCMP load balancing mode. In this mode, the weight of those next hop IP addresses
whose weight is not configured is 1 by default.
Differences between set ip next-hop and set ip default next-hop: After the set ip next-hop command is
configured, the policy-based routing takes precedence over the routing table; while after the set ip
default next-hop command is configured, the routing table takes precedence over the policy-based
routing.
Use this command to customize a default route for a specified user. If the software fails to find the
forwarding route, the packet will be forwarded to the nexthop set with this command.
To use the policy-based routing, you must specify the route map for it and create the route map. A
route map contains multiple policies, and each policy defines one or more match rules and the
corresponding operations. After policy-based routing is applied to an interface, the packets received
by the interface will be checked. The packets that do not match any policy in the route map will be
forwarded through the usual route. The packets that match a policy in the route map will be processed
according to the operation defined in the policy.
A route-map policy may contain multiple set operations.
Examples
The following example forwards the packets from two different nodes through different routes.
For the messages received on the synchronous interface 1 from 1.1.1.1, if the software cannot find
the forwarding route, they are forwarded to device 6.6.6.6. For the messages received from 2.2.2.2, if
the software cannot find the forwarding route, they are forwarded to device 7.7.7.7. The other
messages will be discarded if the software cannot find the forwarding route.
