Hi,
I was trying the following scenario in my GNS simulator. I could not see bgp community attribute taking effect. Please let me know what is going wrong here.
|R7|------|R5|
R7:

As shown above, I am not seeing community attribute on R5 even when I configured route-map on R7. Could you please let me know your thoughts on this.
