Re: sh ip route

caveat as ever is to check if the bgp peer supports route-refresh
capabilities in the initial peering exchange as it's required to
support received-routes option, to check this do a show ip bgp neig
command

will be similar to below

 Neighbor capabilities:
    Route refresh: advertised and received(new)
    Four-octets ASN Capability: advertised and received
    Address family IPv4 Unicast: advertised and received
    Multisession Capability: advertised and received

if it does most newer IOS's do and that command suggests "soft inbound
reconfiguration is not configured" then try it on real hardware
assuming it doesn't work & your using iou/gns environments...

otherwise i'd do show ip bgp summary and look out for state/prefixes
column for how many prefixed received from the peer / or if you have
access to the advertising router run the same command but ending
advertised-routes to see what's it's advertising & on the receiving
router run a debug ip bgp updates to see what it's receiving.....

the regular expression below would still show you neighbor & interface
outputs using the or variable, ok?
