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
•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 | (Optional) RIP v2 enables simple |
Password | 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 VT2142, 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
