But I don't think that in real lab they have T verssion,
One of my friend appered for exam last week,he said all were 12.2 mainline
So in that case,is there any other way to do other then bgp inject map ?

I posted a working config a while back. Look through the archives.
Inject-map is supported on 2600's. It's a bit problematic but it works.
Here's a repost.

Group,
I'm using "IOS Version 12.2(15)T10" on a 2600 and injection maps are
supported, despite the contradictory information on the DOC CD. See below:

It did not work for me either. After doing a tiny bit of research, I concluded it was not supported
<snip> The BGP Conditional Route Injection feature is supported by all platforms in Cisco IOS Release 12.2(14)S that support BGP:
a.. Cisco 7200 series b.. Cisco 7400 series c.. Cisco 7500 series </snip>
