| GREAT BGP RESOURCE!!!!!
http://www.cisco.com/univercd/cc/td...ics/icsbgp4.htm
but it's raised a couple of questions, and it does have a few errors 
in bgp router config you do
network 192.168.0.0
to tell it to advertise said network.
OK, good. Later on they use this form of the network command:
network 160.0.0.0 mask 255.0.0.0
without explaining what mask does and why you would use it.
OK now a redistribution question. It says in a particular situation (page 40 if you have the doc handy) OSPF needs to be redistributed into BGP but then it has the commands:
router ospf 10
redistribute bgp 100 metric 2000 subnets
It seems to me that this is redistributing BGP into OSPF, not the other way around, and what does the subnets word do and what if you left it off???
A few more questions: in one case it states
Router X (running BGP & OSPF) will not synchronize with OSPF because of mask differences. Can someone explain that?
Also, many times in this document it says don't do X because it could make routing loops but it doesn't give examples.
Finally, what is the difference between a NiMH battery charger and a NiCad battery charger? What if you used the wrong kind? | |

| my printer is getting quite a workout these days.
but the bgp doc probably won't answer the battery charger question.  | |

| Another good resource is "Routing TCP/IP vol II" by Cisco Press | |

| Hi,
The most important reference source are:
Internet Routing Architectures; 1st and 2nd editions by Sam Halabi.. Cisco Press. You can find fair prices on these at www.bookpool.com. Another place to get a better feel for ISPs is www.boardwatch.com
It's a very interesting subject and lots to learn. Enjoy. |
