Hi group,
I almost finished Lab 18 except this tiny problem. R1 has a serial
connection over FR with R2 (200.200.200.2) . They can ping each other they
can exchange IPX routes but they can not establish an OSPF neighborship and
BGP neighborship. I found the reason but could not get the logic behind it.
When I remove ip nat outside from interface s0/0.3 problem disappears all
peer establishments become OK. But why ? I need this NAT thing on that
subinterface . I think I am missing a point.
Any ideas ?
