Fa diferenta dintre IPS/SPX
si FRAME RELAY
1. Unde se aplica IPX/SPX -dupa ce iti raspunzi treci la urmatoarea
intrebare
2. la ce Layer lucreaza IPX/SPX
3. La ce foloseste IPX/SPX si cu cine e echivalent in stiva TCP/IP
4 LA ce Layer lucreaza Frame RELAY si in ce configuratii

<problema>
1.To enable IPX routing , use the #ipx routing in global configuration
mode. The full syntax of the command is
#ipx routing [node]
The argument node indicates the node number of the router. This is a
48-bit value represented by a dotted triplet of four-digit hexadecimal
numbers (xxx.xxxx.xxxx). If you omit node, the router uses the hardware
MAC address currently assigned to it as its node address.
Ce legatura e intre rutare (level3) si node address (sau adresa data
link seriala)care e level2? Ce nevoie am de node?
<nelamurirea>
Daca sugerezi ca IPX fiind de level 3 OSI am nevoie de un fel binding
static intre level 2 si 3 pentru adresare, trebuie sa mentionez ca nu e
nici un fel de tabela statica setata gen ARP care sa spuna care e si
asocierea intre adresele level 2 si 3 pentru vecini ca sa stie nodul ce
adresa level 2 sa puna in frame cand vrea sa trimita un packet catre o
adresa level 3

2.OK. Ethernet e retea cu difuzare iar Frame Relay e orientata conexiune
deci punct la punct.
Comparatia propriu-zisa nu este intre layer 2 si 3 ci la configurarea
interfetei :ex.  #interface serial 0 point-to-point  vs. #interface
ethernet 0. De ce si cand folosesc specificatia
point-to-point/multipoint?
