Hi,
I'm doing the bootcamp lab 13 Section 2 Task 3 (last task) and found
something that puzzle me.
Why the host route of BRI interface appeared in the routing table of all the
routers in the diagram after the ATM0/1/0 shut down and ISDN being kick in.
what is the reason of the host route appear ?
Is it normal ?
This recall me when I did the ISDN demand circuit for OSPF routing in other
practise lab, the host route for the BRI interface is also appeared in the
routing table, why ?
One more question on this lab is that :
Is "redistribute static" in R5 & R6 needed in this case (as provided by the
solution)?? since the network 172.16.56.0 (for BRI Inter) already
participate in the EIGRP process on R5 & R6, the rest of the routers will
have full connectivity to all the network after BRI came up, therefore I
don't understand why we need to redistribute static at R5 & R6. ?
I'm posting the config for R6 & R5 and at the same time the route table for
R8 for bootcamp lab 13.
APPRECIATE your input.
Thanks in Advance.
