Use the next-hop-interface command, followed by the index number of the entry
●
in the next hop list, to define an interface as a next hop. You can optionally apply
tracking to monitor the route.
You can also use the name command to assign a name to the next hop list.
Note:
You cannot use a Fast Ethernet interface as an entry on a next hop list unless the
Note:
interface was previously configured to use PPPoE encapsulation, or a GRE
tunnel, or was configured as a DHCP Client. See
page 225, Configuring GRE tunneling
client on page 180.
A next hop list can include the value NULL0. When the next hop is NULL0, the G250/G350
drops the packet. However, you cannot apply tracking to NULL0.
The following example creates next hop list 1, named "Data to HQ", with three entries:
The first entry is IP address 172.16.1.221. Object tracker 3 is applied to monitor the
●
route. For details about configuring the object tracker see
configuration
The second entry is Serial interface 2/1:1.
●
The third entry is NULL, which means the packet is dropped.
●
G350-001(super)# ip next-hop-list 1
G350-001(super-next hop list 1)#name "Data_to_HQ"
Done!
G350-001(super-next hop list 1)#next-hop-ip 1 172.16.1.221 track 3
Done!
G350-001(super-next hop list 1)#next-hop-interface 2 Serial 2/1:1
Done!
G350-001(super-next hop list 1)#next-hop-interface 3 Null0
Done!
G350-001(super-next hop list 1)#

This example demonstrate a case where the data traffic is sent over the WAN Fast
Ethernet interface through the Internet. When the track detects that this next hop is not
valid, traffic is routed over the Serial interface.
