bgp communities lab

[taborn]

I am studying for CCIE-RS and doing all the case studies within routing tcp/ip vol 2 by Doyle and Carroll.

The first lab that is being released is on BGP communities (pg 270).

Topology

1/
From AS2000 advertise 10.2.1.0, 10.2.2.0 and 10.2.3.0/24 into AS100.

2/
Using BGP communities, ensure that AS200,300,400,500,600 do NOT receive the route 10.2.2.0.

Your output should look something like the following (sh ip bgp on router NEVADA):

NOTE: The file should have the configs and the topology. Let me know if it is not right and I will re-upload it.

BONUS TASKS:
A/
As the book states, from AS2000 you are controlling what AS100 does. Suppose you did want to advertise 10.2.2.0 to Nevada. How would you do this using community configurations on router Idaho?

B/
If you have completed task A, Nevada should have all three routes. At present, Idaho is advertising all three routes to Colorado. How would you influence (from Idaho router) Colorado in such a way that he (Colorado router) advertises only 10.2.2.0 to Nevada and does not advertise 10.1.1.0 and 10.1.3.0? (HINT: use no advertise on Idaho router).

Dear All,

NX-OS route distribution require a route-map.

So, I am trying to redistribute lot of connected and static routes to BGP in a VRF.

Is there any solution without making a prefix-list with all the static and connected subnets ?

I tried the configuration below but it does not work :

route-map static-to bgp permit 10

match route-type local

Any idea, please ?

Thanks
