Configuring IP routes
If you set the Private parameter to Yes in a Connection profile, the router does not disclose its
route in response to queries from routing protocols.
Example of RIP and ICMP configuration
The following sample configuration instructs the MAX to ignore ICMP Redirect packets, to
receive (but not send) RIP updates on the Ethernet interface, and to send (but not receive) RIP
updates on a WAN connection.
1Open Ethernet > Mod Config > Ether Options.
2Configure the MAX to receive (but not send) RIP updates on the Ethernet interface:
Ethernet
Mod Config
Ether options…
RIP=Recv-v2
Receiving RIP updates on the Ethernet interface means that the MAX learns about
networks that are reachable through other local routers. However, it does not propagate
information about all of its remote connections to the local routers.
3Exit the profile and, at the exit prompt, select the exit and accept option.
4Set ICMP Redirects to Ignore:
ICMP Redirects=Ignore
5Exit the profile and, at the exit prompt, select the exit and accept option.
6Open the Connection profile in which the link is configured, open the IP Options
subprofile, and configure the MAX to send (but not receive) RIP updates on the link:
Ethernet
Connections
Connection profile 1
IP options...
RIP=Send-v2
Sending RIP on a WAN connection enables the remote devices to access networ ks that ar e
reachable through other local routers. However, the MAX does not receive information
about networks that are reachable through the remote router.
7Exit the profile and, at the exit prompt, select the exit and accept option.
ICMP Redirects ICMP Redirect packets enable the MAX to dynamically find the most
efficient IP route to a destination, but they are one of the oldest and
least secure route discovery methods on the Internet. ICMP Redirect
packets can be counterfeited to change the way a device routes
packets. Therefore, the ICMP Redirects parameter is set to Ignore by
default. Change the setting to Accept if you want to accept these
packets.
