Would also like to add to this that the PE<->CE BGP relationship is eBGP before anybody asks.

Am not having much joy nailing this one down, although an upgrade has resolved it.

12.2(28)SB6 on 7200 PE, have a vrf with combination of static routes and routes learnt from a BGP peer (a CE router)

When configuring "route-target export xxxx:yyyy" , all static, connected and BGP routes are happily exported with the correct extended community RT:xxxx:yyyy, however, when configuring the following route-map:

!
route-map foo
 set extcommunity rt xxxx:yyyy
!
ip vrf foo
 export map foo
!

only static and connected routes are tagged, the BGP routes from the CE are not tagged.

Upgrade to 12.2(31)SB12 fixed this, the only thing I can find which may be this bug is CSCse26921 (BGP route is not updated with newly configured route-target) , but content for this is vague and also states that it has not been observed in 12.2S (and derrived?) trains but lists the affected release as affected (so the rogue code is present?) but has no first-fixed-in for SB or SRC :(

It was therefore a gamble to take to upgrade test PE to latest 12.2SB but seems to have paid off.

Allthough I'm happy that is is fixed, would like to be sure that this is the bug since I need to re-review all 12.2(28)SB boxes in the network.

Many thanks,

Dave.
