Configuring policy-based routing

Next hop lists

PBR rules include a next hop list. When the rule matches a packet, the G250/G350 routes the
packet according to the specified next hop list.
Each next hop list can include up to 20 entries. An entry in a next hop list can be either an IP
address or an interface. The G250/G350 attempts to route the packet to the first available
destination on the next hop list. If every destination on the list is unavailable, the G250/G350
routes the packet according to destination-based routing.

Modifying next hop lists

To modify a next hop list, you must enter the context of the next hop list. To enter a next hop list
context, type the command ip next-hop-list, followed by the number of the list you want to
edit. For example, to modify next hop list 1, type ip next-hop-list 1.
To show the next hops in an existing list, enter the context of the next hop list and type show
next-hop.

Adding entries to a next hop list

1. Enter the context of the next hop list.
2. Use one of the following commands:
- To enter an IP address as a next hop, use the next-hop-ip command, followed by
the index number of the entry and the IP address. You can optionally apply tracking to
monitor the route. For example, the command next-hop-ip 2 149.49.200.2
track 3 sets the IP address 149.49.200.2 as the second entry on the next hop list
and applies object tracker 3 to monitor the route.
- To enter an interface as a next hop, use the next-hop-interface command,
followed by the index number of the entry and the name of the interface. You can
optionally apply tracking to monitor the route, except for the NULL0. For example, the
command next-hop-interface 3 Serial 5/1:1.1 sets Serial 5/1:1.1as the
third entry on the next hop list.

Deleting an entry from a next hop list

1. Enter the context of the next hop list.
2. Use one of the following commands:
- To delete an IP address, use the no next-hop-ip command, followed by the index
number of the entry you want to delete. For example, the command
no next-hop-ip 2 deletes the second entry from the next hop list.
