I have 2 routers running BGP:
R7 config~~~~~~~~~~~~~~~~~~~~~~~~~~~
router bgp 700
redistribute connected route-map t1
neighbor 20.20.20.5 remote-as 500
neighbor 20.20.20.5 send-community
route-map t1 permit 10
set community no-export
~~~~~~~~~~~~~~~~~
but from the BGP table, I cannot see the "no-export" attribute:
R7#sh ip bgp 6.6.6.6
BGP routing table entry for 6.6.6.6/32, version 2
Paths: (1 available, best #1, table Default-IP-Routing-Table)
Advertised to non peer-group peers:
20.20.20.5
Local
0.0.0.0 from 0.0.0.0 (8.8.8.8)
Origin IGP, metric 0, localpref 100, weight 32768, valid, sourced, best
R7#
why I cannot see it?

It appears that prefix 6.6.6.6/32 is originated via a network statement because of its Origin attribute being set to IGP. Can you confirm that.
If it is the case then it this normal that the community no-export is not set on this prefix since the route-map t1 is configured on the "redistribute connected" statement.
You could also use the route-map t1 on the netwrok statement to solve this issue.
Hope this helps,

This doesn't look normal indeed. What version of IOS is running on this box?
