HP 7102dl - ProCurve Secure Router Configuration Manual page 865

You can specify multiple next hop addresses or forwarding interfaces in a
single command. For example:
ProCurve(config-route-map)# set ip next-hop 10.1.1.1 10.2.2.1
The router first attempts to forward a selected packet to the first address or
interface specified. It then tries the second, and so forth.
You can also enter multiple set commands. The router processes the com-
mands in the order indicated in Table 15-19. That is, the router first attempts
to route a packet to an adjacent neighbor. If the router does not know how to
reach that neighbor, or if the forwarding interface for the route to that
neighbor is down, the router attempts to route the packet to transmit the
packet to any secondary specified next hop address. The router would then
attempt to route the packet through a specified interface and so forth.
For example, you could configure two set commands in a route map entry
that selects traffic with IP precedence 5:
ProCurve(config-route-map)# match ip precedence 5
ProCurve(config-route-map)# set interface ppp 1
ProCurve(config-route-map)# set ip next-hop 10.3.3.1
The first set command specifies that the router forward the high-priority
traffic through PPP interface 1. The second command specifies that the router
forward the high-priority traffic to an adjacent device with the address
10.3.3.1.
The route map is applied to Ethernet interface 0/1.
