I have received a route from my neighbor peer as follows,

Network                    Next Hop        Metric LocPrf Weight RouteTag Path
*> X.X.X.X/22          198.32.231.X                                                             X    i <-/->
*> X.X.X.X                198.32.231.X                                                             X    i <-/->
*> X.X.X.X                198.32.231.X                                                             X    i <-/->
*> X.X.X.X                198.32.231.X                                                             X    i <-/->
*> X.X.X.X                198.32.231.X                                                             X    i <-/->

 

I have received the Network X.X.X.X/24 along with the subnet and also received X.X.X.X network with no any subnet mask. why the X.X.X.X network is not advertised with no subnet mask

Hi @amish1

 

A bit more clarity into this would be helpful. 

 

Are you trying to advertise the received bgp network to another BGP neighbor? 

 

Thank you.

Hi sagha,

                No when i check the received routes from the command

#get router info bgp neighbours X.X.X.X received-route

i get this output

Network                    Next Hop        Metric LocPrf Weight RouteTag Path
*> X.X.X.X/22          198.32.231.X                                                             X    i <-/->
*> X.X.X.X                198.32.231.X                                                             X    i <-/->
*> X.X.X.X                198.32.231.X                                                             X    i <-/->
*> X.X.X.X                198.32.231.X                                                             X    i <-/->
*> X.X.X.X                198.32.231.X                                                             X    i <-/->

 

The route received from client is X.X.X.X without any subnet mask

Hi @amish1

 

This needs to be checked on the device advertising this. Could you please check there first? It is also a FGT device? 

 

Thank you.
