Assuming the host routes aren't being manually filtered they should be
passed on. Look at the "show ip bgp 192.168.10.91 255.255.255.255"
output and see what it says about it being advertised. Also are you
sure that these host routes are best routes?

Subject: route advertise in BGP

Dear all,

I have a question on BGP, can anyone help?

A router running BGP AS 200 is receiving from its ebgp peers (AS 100)
with 2
host routes. 192.168.10.91/32 and 192.168.10.92/32.

Then it advertise another route using the network command with the
followings.

router bgp 200
network 192.168.10.0 mask 255.255.254.0

What routes will be distributed to another eBGP peer (AS 300)? I found
that
only a single route 192.168.10.0/23 which is originated from AS 200 is
advertised to AS 300, is it correct?
