Configuring the router
A static route can have both via interface and IP addressed next-hops, with a maximum of three
next-hops. If such a combination is required, separate ip route commands should be used
for the via interface static route and the IP addressed next-hop routes. Also, if more than one via
interface next-hops are required, each must be configured by separate ip route commands.
Note:
You cannot define a static route through the Fast Ethernet interface unless the
Note:
interface was previously configured to use PPPoE encapsulation or was
configured as a DHCP Client. See
Configuring DHCP client
Permanent static route
The Avaya G250/G350 Media Gateway enables you to configure a static route as a permanent
route. Configuring this option prevents the static route from becoming inactive when the
underlying Layer 2 interface is down. This prevents routing table updates from being sent each
time an interface goes up or down when there is a fluctuating Layer 2 interface on the static
route. Configure the permanent option using the ip route command.
For example, the command ip route 193.168.10.0 24 serial 2/1:1 permanent
creates a permanent static route to the network 193.168.10.0 24 via the Serial 2/1:1 interface.
Permanent static routes should not be configured over Serial Layer 2 interfaces that participate
in a Primary-Backup pair. For more information on Backup interfaces, see
page 232.
Note:
You cannot configure tracking on a permanent static route.
Note:
Discard route
Discard route enables you to prevent forwarding traffic to specific networks. You can configure a
static route that drops all packets destined to the route. This is called a discard route, indicated
by the null0 parameter, and is configured using the ip route <network> <mask> null0
command.
For example, the command ip route 134.66.0.0 16 Null0 configures the network
134.66.0.0 16 as a discard route.
Note:
You cannot configure tracking on a discard route.
