I don't see how you would end up advertising the route. With the prefix-list
you are just allowing it.
I can see three options:
--Aggregate command
--"auto-summary" + "network 156.1.0.0" under the bgp process.
--you summarise in igp and redistribute it into bgp ,
As the first two options use bgp summary features I would do the last one,

Subject: summary route
If I want to announce a summary route of my internal network towards the
Backbone router, and not allowed to use the route-summary in BGP.
Will the following solution work:
ip prefix-list TOBB permit 156.1.0.0/16 -------------------> Assuming my
internal network is comprise of 156.1.0.0/16 network, and scattered
throughout the netowork with /24 bit mask.
router bgp 100
neighbor 1.1.1.1 remote-as 230
neighbor 1.1.1.1 prefix-list TOBB out
I didn't use the command aggregate-address. I am assuming by saying not use
route-summary means I can't use aggregation.
The implicit deny at the end should block all the longer routes.
Please advise
