How can I see BGP routes filtered with a prefix-list?

[dhawkes]

I have 2 BGP routers peered together, in 2 different ASNs.  I am using prefix-lists on router A, and would like to see what routes are being advertised by router B, even though I am filtering the routes with a prefix-list (without just going to router B and doing a show ip bgp).  How can I see the routes I am filtering, but getting advertised by the far router?  I want to add to my prefix-list, but need to match the advertised route.

Thanks in advance.

from you router you can issue this command to see all the routes received from your neighbor routershow ip bgp neighbors [neighbor-address] [received-routes | routes | advertised-routes | {paths regexp} | dampened-routes]

Hi,

show ip bgp nei ... received-routes

But you will probably need to enable inbound soft reconfiguration on your router by

router bgp ...

nei ...  soft-reconfiguration inbound
