Setting the Maximum Length of RIP Packets

Setting the Maximum Length of RIP Packets

Context

By default, a RIP packet contains 25 routes. Increasing the maximum length of RIP packets can add more routes to the packets. Large RIP packets improve bandwidth use efficiency.

Before using the rip max-packet-length command to increase packet length, ensure that the peer interface accepts the RIP packets longer than 512 bytes.

After the packet length is increased, Huawei devices may fail to communicate with non-Huawei devices. Therefore, use this command with caution.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. On an Ethernet interface, run undo portswitch

    The interface is switched to Layer 3 mode.

    By default, an Ethernet interface works in Layer 2 mode.

    The mode switching function takes effect when the interface only has attribute configurations (for example, shutdown and description configurations). Alternatively, if configuration information supported by both Layer 2 and Layer 3 interfaces exists (for example, mode lacp and lacp system-id configurations), no configuration that is not supported after the working mode of the interface is switched can exist. If unsupported configurations exist on the interface, delete the configurations first and then run the undo portswitch command.

    NOTE:

    If many Ethernet interfaces need to be switched to Layer 3 mode, run the undo portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view to switch these interfaces to Layer 3 mode in batches.

  4. Run rip max-packet-length { value | mtu }

    The maximum length of RIP packets is set.

    mtu indicates the maximum RIP packet length.

    By default, the maximum length of RIP packets is 512 bytes.

  5. Run commit

    The configuration is committed.
