The following describes the menu items in the RIP Configuration screen:
l
RIP Enable
-
Yes
:
RIP is enabled
-
No
:
RIP is disabled.
l
Multicast
Though typically not implemented across the public Internet, Multicast
for IP support is possible across SkyWay 5000 when routing with RIP
v.II is enabled. SkyWay 5000 can be configured to use the multicast
address 224.0.0.9 to proliferate route updates, thus reducing
broadcasts of route updates.
Host groups can be reached across routed segments within the
boundaries of a private inter-network (Multicast as defined by the
Internet Engineering Task Force in RFC 1112) - Multicast is an
addressing implementation to allow for data to be sent one time and
received by a select scope of hosts.
Using Multicast, unnecessary replication of data packets is reduced to conserve
bandwidth.
-
Disable/Enable
: The pull-down choices either enable or
disable multicast option
l
Update Interval
By default, every 30 seconds the SkyWay 5000 router will advertise its
routes to other RIP v.II devices. This value can be changed, but it
must remain a multiple of the value for EXPIRE TIME.
l
Expire Time
By default, 180 seconds will pass after the last route update has
occurred and the SkyWay 5000 will remove its route table entry.
The following describes port configuration related to RIP. Please note that
configuration fields are identical for the Ethernet and RF ports, but can be
configured differently.
l
Authentication Type
-
Clear
: RIP will announce updates and listen for all RIP updates
on the specified interface.
-
Simple
: RIP expects updates to include an authentication key.
The key will be transmitted in clear text.
-
MD5
: (per RFC 1321 {MD5 Message Digest Algorithm} & RFC
2082 RIP-2 MD5 Authentication) route update authentication
keys are entered by user as plain text. Keys are taken as
input by the MD5 algorithm and output as a 128-bit
"fingerprint" or "message digest"
l
Authentication Key
Enter the key to be used for authentication for the given port
l
Send Mode
-
Version 1
: sends only RIP version 1 updates.
-
Ver1 Compatible
: sends version 2 updates but will listen for
version 1 (if MULTICAST is enabled only version 2 is used).
-
Version 2
: sends RIP Version 2 updates only, no backwards
compatibility.
