Configuring Multiple Next-Hops; Deleting A Route And Its Next-Hops; Via-Interface Static Route - Avaya G250 Administration

Configuring multiple next-hops

You can configure up to three next-hops for each static route in one of the following manners:
Enter all of the next-hops using a single ip route command. To add a new next-hop to
●
an existing static route, enter the new next-hop individually, as in the following option.
Enter each next-hop individually with it's own ip route command.
●
Note:
If you apply tracking to a static route, you can only configure one next-hop for the
Note:
route.
Next-hops can only be added to an existing static route if they have the same preference and
metric as the currently defined next-hops.
Note:
Metrics are used to choose between routes of the same protocol. Preferences are
Note:
used to choose between routes of different protocols.

Deleting a route and its next-hops

Using the no ip route command deletes the route including all of its next-hops, whether
entered individually or with a single command. For example, to specify next-hops 149.49.54.1
and 149.49.75.1 as a static route to the network 10.1.1.0, perform one of the following:
Use the single ip route 10.1.1.0 24 149.49.54.1 149.49.75.1 command
●
specifying all next-hops together,
Or
Use the individual ip route 10.1.1.0 24 149.49.54.1 and ip route 10.1.1.0
●
24 149.49.75.1 commands.

Via-interface static route

PPP and frame relay allow for a Layer 3 interface to be established without knowing in advance
the next-hop on the other side of a serial link. In this case you can specify a Serial Layer 2
interface or a GRE tunnel as a next-hop instead of providing a specific next-hop IP address.
This is equivalent to specifying the node on the other side of the serial link as the next-hop when
its IP address is unknown. The via interface option is configured by specifying the type and the
number of the serial interface using the ip route command.
Note:
The interface used in the via route must have an IP address attached to it.
Note:
For example, the command ip route 193.168.10.0 24 serial 2/1:1 creates a static
route to the network 193.168.10.0 24 via the Serial 2/1:1 interface.
