BGP Advertisement Question

[Junaid Shah]

Hello,

I have a question regarding BGP advertisement, I have a /24 network for instance 192.168.0.0/24 that i want to advertise through BGP but i want to skip a /32 or /30 ip from this range from advertisement for example i want to advertise 192.168.0/24 but not 192.168.50.0/30.... is there a way i can do that... Please assist. Thanks

you can directly use the network statement to use /24 that BGP accepts. ( issue if you like to advertise /32 and /30 length)

also, your example not matches the IP range ?

 want to advertise 192.168.0/24 but not 192.168.50.0/30.     (192.168.50.0/30 is not part of /24 range)

or are you looking for any /32 /30 connect not to announce to peer ?

what is the use case here - do you have any connected interface /30 or /32?

you can filter the list If you like:

sorry there is no way as I know 
config static route to null for this /32 make traffic drop. 
the only way I see is divide /24 into /25 and make the host with /32 in specific part and not advertise it and advertise other parts
but still here issue is that the  SP can not accept less than /24.
