In typical applications, you send the sampled packets to an analyzer or a workstation for analysis, rather than another router. If you must send this traffic over a network, you should use tunnels. For more information about tunnel interfaces, see Tunnel Interfaces Configuration Guidelines.
If your router is equipped with a Tunnel PIC, you can forward duplicate packets to multiple interfaces by configuring a next-hop group. To configure a next-hop group, include the next-hop-group statement at the [edit forwarding-options] hierarchy level:
-
next-hop-group [ group-names ] {
-
-
interface interface-name {
-
next-hop [ addresses ];
- }
- }
The interface statement specifies the interface that sends out sampled information. The next-hop statement specifies the next-hop addresses to which to send the sampled information.
Next-hop groups have the following restrictions:
