By default, every 30 seconds the SkyWay 4000 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.
• Expire Time
This field defines how long the route table entries remain in the
SkyWay 4000 route table. The default is 180 seconds.
The following describes port configuration related to RIP. Please note that
default configuration fields are identical for the Ethernet and RF ports, but can
be configured differently.
• 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"
• Authentication Key
Enter the authentication key for the given port.
• 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.
- None: will still listen for and process updates but will not send
any updates on this interface
l Receive Mode
- Version 1: listens for and will update self with version 1
updates only.
- Version 2: listens for and will update self with version 2
updates only.
- VERSION 1 & 2: listens for and will update self with version 1
& version 2 updates
• RIP Default Metric
- 1: at the default, this SkyWay interface believes it is one hop away
from the nearest gateway interface. Increasing this value by single
digit orders this routing interface to let all other RIP-enabled routers
believe that it is a secondary or higher cost path (typically used for
redundancy).
After changes are complete, click on the Update button. If a mistake is made,
you can restore the previous setting by clicking the Reset button. To make
changes effective, reboot the unit by clicking on Advanced -> Reboot from the
Navigation Toolbar.
