MLPPP Fragmentation Guidelines

Use the following guidelines when you configure MLPPP fragmentation on a link interface:

• Configure the same fragmentation setting—enabled or disabled—for all member links in a bundle.
• When fragmentation is enabled, configure the same fragment size for all member links in a bundle.
• Make sure a link’s fragment size does not exceed its maximum transmission unit (MTU) size.
• Do not configure both MLPPP fragmentation (with the ppp fragmentation command) and IP fragmentation of L2TP packets (with the ip mtu command) on the same interface. Instead, you must choose only one of the fragmentation configurations by setting it to the necessary value and set the other fragmentation configuration to the maximum allowable value.
