For MLPPP, the sequence header format is set to 24 bits by default. You can configure an alternative value of 12 bits, but 24 bits is considered the more robust value for most networks.
To configure a different sequence header value, include the short-sequence statement:
You can include this statement at the following hierarchy levels:
For MLFR FRF.15, the sequence header format is set to 24 bits by default. This is the only valid option.
