Configuring IP Routing
Configuring the MultiVoice Gateway for dynamic route updates
Example of route preferences configuration
The following example increases the preference value of RIP routes, instructing the router to
use a static route first if one exists.
1
Open Ethernet > Mod Config > Route Pref.
2
Set Rip Preference to 150:
Ethernet
Mod Config
Route Pref…
Rip Preference=150
3
Close the Ethernet profile.
Configuring the MultiVoice Gateway for dynamic route
updates
The Ethernet interface can be configured to send or receive RIP updates, send or receive OSPF
updates, and accept or ignore ICMP redirects. All of these routing mechanisms modify the IP
routing table dynamically.
The following example shows the parameters that enable the MultiVoice Gateway to receive
updates from RIP or ICMP. (For information about OSPF updates, see Chapter 9, “Configuring
OSPF Routing.”)
Ethernet
Mod Config
Ether options…
RIP=On
Ignore Def Rt=Yes
RIP Policy=Poison Rvrs
RIP Summary=Yes
ICMP Redirects=Accept
Understanding the dynamic routing parameters
This section provides some background information about the dynamic routing options. For
complete information, see the MAX Reference Guide.
RIP (Routing Information Protocol)
The RIP parameter enables the MultiVoice Gateway to send or receive RIP updates (or both)
on the Ethernet interface. You can also choose between RIP-v1 and RIP-v2 on the Ethernet
interface.
Note:
The IETF has voted to move RIP-v1 into the historic category and its use is no longer
recommended. Ascend recommends that you upgrade all routers and hosts to RIP-v2. If you
must maintain RIP-v1, Ascend recommends that you create a separate subnet and place all
RIP-v1 routers and hosts on that subnet.
