I recently upgraded to IOS 11.2(12)P and I'm having some trouble with
route-maps taking.  I'm wondering if anyone has had a similar incident:

neighbor 205.150.206.65 route-map UUNET in
neighbor 206.47.45.128 route-map BGS in
!
ip as-path access-list 100 permit _816_ 
ip as-path access-list 100 permit _701_

ip as-path access-list 100 permit _3602_ 
ip as-path access-list 100 permit _1239_ 
ip as-path access-list 100 permit _6463_
ip as-path access-list 100 permit _2493_
ip as-path access-list 100 permit _174_
ip as-path access-list 101 permit .*

c7# sh ip bgp reg 701

33 i
*                   206.47.45.128                60      0 3804 577 6453
701 33 i
*>                  205.150.206.65               60      0 816 701 33 i

The path 3804 577 6453 33 should have a local preference of 50
(access-list 100), not 60! (access-list 101) 
Path 816 701 33 is correct at 60 (access-list 111)

c7# sh ip bgp reg 3561
*  12.10.14.0/23    206.47.45.128                60      0 3804 577 3561
10815 ?
*>                  205.150.206.65               60      0 816 701 3561
10815 ?

It looks as though it is tagging everything as .*.. but this is odd.  It
tagged this route properly:

*  24.231.0.0/19    206.47.45.128                50      0 3804 577 3561
2493 2493 8160 8160 i

Anyone have any ideas?!  I've done clear ip bgp xxx soft in but not
clear ip bgp xxx I was running 11.2(5) before which had an route cache bug
so I'm used to doing a clear ip cache after each reload.  Did that too,
and nothing.
