Enabling the Pipeline to use dynamic routing
In addition to RIP, the Pipeline can use Internet Control Message Protocol
(ICMP) Redirects to acquire routes dynamically. ICMP dynamically determines
the best IP route to a destination network or host and uses ICMP redirect packets
to transfer packets over a more efficient route. ICMP redirect packets are one of
the oldest route discovery methods on the Internet and one of the least secure,
due to the possibility of receiving counterfeit ICMP redirects. You can configure
the Pipeline to ignore ICMP redirects to promote security.
To ignore ICMP redirects:
1
Open the Ethernet > Mod Config menu.
2
Make sure that ICMP redirects are not accepted.
ICMP Redirects=Ignore
3
Close and save the profile.
If you are using RIP-v1
The Internet Engineering Task Force (IETF) voted to move RIP-v1 into the
“historic” category so its use is no longer recommended. You can upgrade all
routers and hosts to RIP-v2. If you need to maintain RIP-v1, create a separate
subnet and place all RIP-v1 routers and hosts on that subnet.
Note:
RIP Policy and RIP Summary are relevant only to RIP-v1 and should not
be set when interacting with RIP-v2 routers.
If the Pipeline Ethernet interface is on a RIP-v1 subnet:
1
Open the Ethernet > Mod Config > Ether Options menu.
2
Turn on RIP-v1.
For example:
RIP=Both-v1
This setting means that the Pipeline transmits and receives RIP-v1 updates
on the local Ethernet. If you do not want the Pipeline to be informed about
local routing changes (for example, if all local routing is handled by a default
router), you can use the following setting instead:
RIP=Send-v1
