Question for you BGP mavens:

Given...

<snip>
router bgp 100
 no synchronization
 neighbor 54.1.7.254 remote-as 54
 neighbor 54.1.7.254 route-map prepend out
 neighbor 204.12.1.254 remote-as 54
 no auto-summary

ip as-path access-list 1 permit _45$

route-map prepend permit 10
 match as-path 1
 set as-path prepend 100 100
route-map prepend permit 20
<snip>

How would one verify the attachment of the extra as-paths as advertised to
the backbone router?

This config works but I had to go to the backbone to verify it.

All I can think of is doing show ip bgp regexp to verify that there's a
route originating in AS 45 and that I used the right expression.

Is there something else I could check on R6?
