optimization of routes in an environment that uses multiple routing protocols. For example, when
RIPv2 is being run on a network along with another IGP, and one router is running both protocols, then
that router can indicate to the other RIPv2 routers that a better next-hop than itself exists for a given
destination.
The Authentication group is the RIPv2 mechanism for authenticating the sender of the routing
eliminates the vulnerability of the routing infrastructure. This authentication scheme is essentially the
same mechanism provided by OSPF. Currently, only a plain-text password is defined for
authentication.
For Plain Text RIPv2 authentication, the maximum length of the password is 16 characters; however,
Message Digest authentication can have a key id field of up to 50 characters.
If the RouteFinder is configured for Frame Relay, the IP Port Setup dialog box displays a single WAN
tab. Logical WANs are established in this dialog box and are mapped to DLCIs in the Frame Relay
DLCI dialog box. Mapping DLCIs to logical WANs using IP requires an IP Address and IP Mask in the
Port Address group; and, it requires an IP Address in the Remote Address group. When assigning IP
addresses, the Port Address and Remote Address must be in the same network segment.
To add logical WANs in a frame relay configuration, click the Add button and the next WAN number is
displayed in the List of Logical WANs window. Make the appropriate Port Address and Remote
Address assignments and click Save. You can also edit a logical WAN address by clicking on the
logical WAN in the List of Logical WANs window, changing the Port Address and Remote Address
assignments and clicking Save. To delete a logical WAN, highlight the WAN number in the List of
Logical WANs and click the Delete button.
Once the logical WANs are established, you must go to the Frame Relay DLCI dialog box to map the
logical WANs to a DLCI.
