   Howard and Others,
       Just when I thought I had a firm grasp on BGP, I am having
   problems. I have 3 days till I take my lab and I need to get the BGP
   bug worked out. I understand you are an unofficial "expert" on BGP.
   Here are a few questions if you don't mind Howard. BTW, I met you a
   couple of months ago in Novi, Michigan when you gave a lecture/seminar
   on Crypto/Security. Excellent topic. Anyway....
   
   First of all, I have the following senario:
   
                    ( RUNNING OSPF ) RUNNING EIGRP
     AS1 ( AS2 ) AS3
   routerA--------routerB--------routerC--------routerD-------routerE
   
   EBGP between A and B, D and E
   IBGP between B and D
   
   On routerA I have statically injected networks 192.168.1.0 and
   192.168.7.0
   They are reflected in the BGP table on A,B,and D, but not E. This is a
   problem is it not? I verified E is an Estab. neighbor with D.
   
   Also, on RouterB, the networks 1.0 and 7.0 show up in the routing
   table. However, they do not show up in D's routing table. I believe
   that in order for them to be injected into the rest of the network, I
   need to redistribute at B from ospf<-->BGP. Correct?
   
   As well, at D, I would need to redistribute OSPF<-->BGP, not
   forgetting to apply route-maps so AS1 and AS3 don't see each other if
   I don't want them to. Right?
   
   Thanks for your help.
