number of 900.
Setting Load Distribution for Next-hop Gateways
You can specify up to four next-hop gateways in an ip-policy statement. If you specify
more than one next-hop gateway, you can control how the load is distributed among
them. You can cause each new flow to use the first available next-hop gateway in the ip-
policy permit statement, or you can cause flows to use all the next-hop gateways in the
ip-policy permit statement sequentially.
To set the load distribution for next-hop gateways, enter one of the following commands
in Configure mode:
Setting the IP Policy Action
You can specify when to apply the IP policy route with respect to dynamic or statically
configured routes. The SSR can cause packets to use the IP policy route first, then the
dynamic route if the next-hop gateway specified in the IP policy is unavailable; use the
dynamic route first, then the IP policy route; or drop the packets if the next-hop gateway
specified in the IP policy is unavailable.

gateway in the ip-policy permit
statement for all flows. This is the
