Dynamic Routing
Dynamic routing enables you to define dynamic routes using Routing Information Protocol (RIP) to exchange
routing information with other network routers across the WAN (Internet) and LAN interfaces.
Dynamic Routing fields
Field
Description
Enable RIP
Enables RIP. Any RIP-enabled router:
•
Sends automatic update packets containing its routing table periodically (every 30 seconds)
•
Adds, deletes, or modifies routes in its routing table based on periodic updates from other routers
•
Responds to requests for its routing table
Protocol
Sets the RIP version:
• RIP v1 (UDP protocol)
• RIP v2 (multicast protocol)
• RIP v1 compatible (UDP protocol with multicast format)
Routers using RIP v1 or a compatible protocol can communicate with each other, but not to routers
using RIP v2.
Enable
Password
(Optional) RIP v2 enables simple plain-text password-based authentication for RIP packets. It is
disabled if RIP v1 is selected.
Password
The password can have up to 16 characters.
Interface
Normally, when it is enabled on a router, RIP dynamically provides routes on all configured interfaces.
On the VT2542, you can select which routes are distributed through the network:
•
LAN
— Sets the direction in which RIP messages are sent on the LAN interface
•
WAN
— Sets the direction in which RIP messages are sent on the WAN interface
The options for LAN and WAN are:
•
Both — receive and send updates to the routing table to other routers on the interface
•
In — receive but do not send routing updates on that interface
•
Out — send but do not receive routing updates on the interface
•
None — do not send or receive routing updates through the interface
