I'm trying to prepend AS numbers to outgoing updates on a router that is originating the routes. When I look at the neighboring router, the AS numbers weren't added. If, from a router not originating the routes, I add the same route-map to an outgoing neighbor, the AS numbers are prepended. I'm using the exact same route-map and access-lists on both routers. Should I be able to prepend an AS path to an IGP neighbor if I am originating the routes? Any ideas?
Visual:
R5 AS 200------------------R2 AS 200--------------R1 AS 8888
R5 originates 172.32.1.0 from a loopback using a network statement. Outgoing route-map to R2 matches 172.32.1.0 and sets as-path prepend to 500 and 501. Clear IP BGP *, then look in R2, no dice. See the route, but not from 500, 501. If I put the same route-map on the R2 for R1 neighbor, R1 sees 500 501.
I'm tearing my hair out! I've triple-checked the configs. I'm running 12.1(5)T9 on all routers. Nothing else special happening with BGP.
Thanks in advance!
