I think you sould use Peer Group for this situation, 10 eBGP peers will
be placed in a group which have the same policies. Individual eBGP peer
can have its own police that have higher precedence than group policy.
This is yours

With route-map you can do many thing even distribute-list and
filter-list could be replaced by route-map, other purposes are set
LOCAL_PREF, MED, Weight, prepending AS_Path ..ect ..
Hope that I haven't made any mistake ;-)

Subject: BGP network statement
yesterday I posted the following question:
I have a quick BGP question.
If R1 has 150.1.0.0/16 in its bgp table, is there a way to advertise
this
route to ONLY ONE eBGP peer. I know you can use distribute-list to deny
and allow certain routes, but if you have 10 eBGP peers (hypothetical
situation) and you I wanted to send this route to R2 only, do I need to
specifically deny that route via an access-list (or prefix-list) all the
other nine peers? Seems like there must be an easier way.
I got back some very good results but it brought up another question. I
noticed that bgp "network" statements have a "route-map" option
and "backdoor" option. I know what "backdoor" is used for, but what kind
of information can be set with the route-map option. Can I use it to
solve the question I posted yesterday (only advertise the route to
specific bgp peers)?
