Adding a static route from a program

[xuoguoto]

Hello all,

I have FRR configured to redistribute static routes and after adding a route like ip route 172.16.210.0/24 192.168.200.10 works fine and is distributed over BGP.

Now I want to add static routes using a program rather than by editing and saving the conf in vtysh. One means is using vtysh itself like vtysh -c "conf t" -c "no ip route 172.16.220.0/24 192.168.200.10".

Is this the recommended way or is there some protocol by which a static route can be added or removed without going via vtysh?

Also is there any way a static route added do not get passed on to kernel to be installed on local routing table? I just want to advertise it via BGP and not to add it locally.

It depends. In most cases, this is the correct way. Otherwise, FRR has gRPC support (experimental, not well-tested though), where you can create static routes via gRPC.

Also is there any way a static route added do not get passed on to kernel to be installed on local routing table? I just want to advertise it via BGP and not to add it locally.

No. But you can do this by changing the next-hop on the criteria. Let's say if sending 10.10.10.0/24, set ip next-hop to something. Look at the route-maps.

When I add a static route in frr using ip route 172.16.210.0/24 192.168.200.10 can FRR add those routes in a separate routing table or even a name space so that it do not pollute the default routing?

Adding a route specifying a table like vtysh -c "conf t" -c "ip route 172.16.220.0/24 192.168.200.10 table 100" adds the route in linux routing table 100, but it does not gets advertised into the neighbour.

I am pretty new to FRR and multiple routing tables in BGP, so I know I am missing stuff big time, just trying to figure out all these

Thanks for the patience!
