while we are on this subject ...Is this lab looking good in terms of the ip
an subnetting ?
http://www.fatkid.com/html/320_basic_bgp.html
Looking at the config , there seems to be an overlap ..
the link between R4 and the term_srv is 192.19.15.0/24 (??) and the same
major net is VLSMed
all over AS 200 ...
Is there a typo or am i missing something very basic ?
appreciate if someone has done this lab before and ur thoughts .
Cheers,Padhu

Subject: An IP addressing sanity check
Hi all,
A little tip while studying. Quite useful when using 5 or more routers...
When you have done your IP addressing for any test labs that you are doing
at home/work etc., type into a text editor each subnet and mask in your
scenario and associate it with a loopback address, for example
int lo0
ip address 172.16.30.10 255.255.255.0
int lo1
ip address 172.16.40.253 255.255.255.252
int lo2
ip address 172.16.40.254 255.255.255.252
Once this is done, copy and paste to one router. If there are any IP rules
broken, the router will highlight this for you as an error, like the above
example would do.
If it accepts all the loopbacks, then you know your IP is OK and you can wr
erase and continue. For 5 mins work, it will put your mind at ease while
troubleshooting any config errors that you may have introduced in your
studywork for the scenario you are doing.
Hope someone finds this useful
Andy
