Multilink PPP best comprehension

With multilink with fragmentation :

Supposing there are 8 B channels ;

One 1500 bytes- IP datagram should be transmitted on the ISDN link.

How will be fragmented ? approximately 1500 bytes/8 ?

Same question with one 64 bytes-IP datagram ... How will be fragmented ? I suppose it won't be fragmented in 8 fragments...

Re: Multilink PPP best comprehension

Thanks for your answer.

But I don't understand, depending on the size of the packets, how the fragmentation is realized by default, in IOS 12.1 for example...

Could you explain me that ?

By default, the packet is divided into X fragments, where X is a power of 2 (1, 2, 4, ...), is less than or equal to the number of links, and doesn't result in fragments less than 30 bytes.
