bgp ip prefix-list question

[fedorafan]

routerA and routerB are bgp neighbors,

On routerA, there is an inbound prefix-list "B-pre", which you can see as below

+++
routerA#sh ip prefix-list B-pre
seq 4 permit a.b.c.240/30 le 32
seq 15 permit a.b.64.0/20 le 32
...etc.
+++

my question is, why the two routes, "a.b.c.240/30" and " a.b.64.0/20" are not getting propagated into routerA?

I can see them in the "received-routes" output, but not in the "sh ip bgp neighbors b.b.b.b route" result.

routerA#sh ip bgp neighbors b.b.b.b received-routes

Network Next Hop Metric LocPrf Weight Path
* a.b.c.240/30 b.b.b.b 0 0 65486 i
* a.b.64.0/20 b.b.b.b 0 65486 i

routerA#sh ip bgp neighbors b.b.b.b route

the result does not have the two routes.

can you post the whole output of the sh ip prefix-list as well as the the BGP configuration on both routers??

Check you the route's origin IP is reachable from Router "B"
if not that would be the reason.
