Need some help on understanding IP fragmentation. In the setup below, are
the steps below correct?
LAN A |
|
Host A_| Serial line 1 Serial line 2
| LAN B
|______e0 R1 s0-------------------s0 R2
s1---------------------------s0 R3 e0 -----------|
|
|
|
|-------Host B
Host A sends 1500 bytes long packet to e0 of R1 (destined for Host B).
R1 s0 has MTU set to 750 bytes. So R1 fragments packet into 2.
R2 has MTU of 375 bytes on s1, R2 fragments packet into 2
R3 has MTU of 1500 on Ethernet LAN B, so it reassembles the fragments into
one 1500 byte long packet & hands it to Host B??
Any references to sites/books will be greatly appreciated.
Many thanks & regards.
