CheckPoint BGP Route advertisement

Hello All,

Yesterday i face strange problem in my checkpoint device CP15400 version R77.30 .

I have configured BGP and BGP neighbor was establish.  i was able to receive routes from neighbor but  i was not able to advertise my Public Pool to my neighbor .  

in route redistribution option i have selected interface where i have configured my public pool and i was redistributing it into my BGP routing protocol . 

Does anyone has come across that situation  ?

Re: CheckPoint BGP Route advertisement

If I am reading this correctly you have established BGP with your peer but are unable to advertise from your Check Point 15400 to the peer.

1.) Do you have a static route on your peer, for the network you are trying to advertise, which is would take a higher priority (admin distance) over the BGP route?

2.) Do you have a route-map/prefix-list on your peer which is only accepting specific networks in?

3.) If your peer is a Cisco, have you run the command 'show ip bgp neighbor <Check Point IP> received-routes'

4.) You can also run on your 15400 'show bgp peer (peer IP) advertise' which will show you if the route is even being advertised out of your 15400. 

Just a few things I can think of with limited information about your config, peers, etc.

1)  The setup is working fine With my Old Nokia hardware.  

2)  Problem is when i do show bgp peer x.x.x.x. advertise in CP i dont see anything even though i have redistributed my Interface IP Network into BGP.

One more additional question to those which are here already... How did you take whole configuration? Was it via WebUI or via CLI?

Re: CheckPoint BGP Route advertisement

Ok, so lets get into some more details. 

1.) What is the AS of your 15400?

2.) What is the AS of your peer?

3.) If you can show a screen shot of your WebUI for the Route Redistribution section?

Re: CheckPoint BGP Route advertisement

Good, are you sure that all the configuration related BGP has been taken via WebUI? Because in case if you do for example routemap in CLI, the following rule could be aplicated.

Routemaps

Control which routes are accepted and announced. Used to configure inbound route filters, outbound route filters, and to redistribute routes from one protocol to another.

Route maps offer more configuration options than the Portal options. However, they are not functionally equivalent.

If one or more route maps are assigned to a protocol (for import or export), any corresponding Portal configuration is ignored.

It is not probably your case but it is good to check this as well.

Hi, 

Make sure that your route is on the Routing table, only routes on the routing table are distributed. 


To be able to help please further please share: 

Routing table of both members, bgp configuration and redistribution options.
