Hi All,
        I think we need to discuss this concept here, cause it confuses me
and I am sure it confuses a lot of ppl.
the question is when to bridge and when not?

through the bootcamp 8 as an example the requirements were to put same
network no. on both sides or router R1 so we have to bridge the ipx over
that router simply by creating bridge 1 and assign it to both interfaces,
clear.

now take a look to this diagram:

The rest of the network <==
R5--S1(net700)--------S0-R1-E0-------(Net700)E0-R7---

I tried to make bridging only on R1 but it didn't work I don't know why?
 the solution is to configure IRB on R5 and bride the S1 on R5 then it will
work!!

I always think of the bridge as a hub but with a table to direct the traffic
to propriate port, but it looks like I am missing some vital principle here.

Can any one clarify why 1st solution didn't work while the second one
worked.
