F3215-HP Load Balancing Module Appendix Protocol Reference-6PW101

9
• IP address—Destination IP address. It can be a natural network address, subnet address or host
address.
• Subnet mask—Mask of the destination address.
• Next hop—If set to 0.0.0.0, it indicates that the originator of the route is the best next hop;
otherwise it indicates a next hop better than the originator of the route.
RIPv2 authentication message format
RIPv2 sets the AFI field of the first route entry to 0xFFFF to identify authentication information.
Figure 3 RIPv2 authentication message
• Authentication type—A value of 2 represents plain text authentication, while a value of 3
represents MD5.
• Authentication—Authentication data, including password information when plain text
authentication is adopted or including key ID, MD5 authentication data length and sequence
number when MD5 authentication is adopted.
RFC 1723 only defines plain text authentication. For information about MD5 authentication, see RFC
2453.
Supported RIP features
The current implementation supports RIPv1 and RIPv2.
