Thanks Mike. According to Doyle's Vol II book page 271-272, he sort of insinuat
es that the "send-community" is automatically sent to IBGP peers by default and
 it's only EBGP peers that you have to use this command.

However while I was waiting for your reply, I was changing routers around which
 are running different IOS images as I thought it was a bug, but I got the same
 result. Once I used the "send-community" command to send the community to IBGP
 peers, the community was propagated.

Thanks for your reply ..... MW

Hi Peoples

I have a question regarding the sending of the COMMUNITY attribute between EBGP
 and IBGP peers. My understanding was that the COMMUNITY attribute is an option
al transitive attribute and is not sent by default. Therefore you need the "nei
ghbor x.x.x.x send-community" command to make this happen.

The million dollar question ..... does this apply to both EBGP peers and IBGP p
eers?

Thanks .... MW :)
