Setting the maximum length of RIP packets
![[NOTE: ]](images/note.png) | NOTE: The supported maximum length of RIP packets varies by vendor. Use this feature with caution to avoid compatibility issues. | |
The packet length of RIP packets determines how many routes can be carried in a RIP packet. Set the maximum length of RIP packets to make good use of link bandwidth.
When authentication is enabled, follow these guidelines to ensure packet forwarding:
For simple authentication, the maximum length of RIP packets must be no less than 52 bytes.
For MD5 authentication (with packet format defined in RFC 2453), the maximum length of RIP packets must be no less than 56 bytes.
For MD5 authentication (with packet format defined in RFC 2082), the maximum length of RIP packets must be no less than 72 bytes.
To set the maximum length of RIP packets:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | interface interface-type interface-number | N/A |
3. Set the maximum length of RIP packets. | rip max-packet-length value | By default, the maximum length of RIP packets is 512 bytes. |
