Hi, Group,

I am stuck in Jeff's route filtering question, (jeff's
book page 799. Question 5, 6, 7 and solution page 961
and 962).

I think that the solution for question 5 is
unecessary because I am not sure why he put a distance
command: distance 170 192.168.10.254 0.0.0.0 1

I think that 192.168.10.254 is running EIGRP, and thus
it is unnecessary to put the command under ISIS
domain?

Router C can learn the route from 192.168.10.254, but
those routes are distributed in router C to ISIS, in
this case, I will say that router C learn ISIS route
from redistribution, not from 192.168.10.254.

Same thing for router D.

Question 6:
 it
seems that the solution to Question 6 is wrong.i tried
and it never
works.

The solution said that you have to configure
dinstance under IS-IS domain with command

distance 255 192.168.10.241 0.0.0.0 1
access-list 1 permit any.

I think that this is not correct because the first
part of the question is to accept routes only from
router A. In the solution, it doesn't show this part.

i think that what the solution has done is just to
answer the second part of the question. Once A fail. D
will not accept any router from router B, But router D
can still accept routes from router B from EIGRP
domain which is not clearly answered by the solution.

Any comments on this or what's the correct solution

As always, your help is always appreciated

Regards

michael
