How to clear or purge routing table ?

Hello,

 

I'm searching how to clear or purge routing table. A few days ago we were using a IP Adr Scope (10.10.3.0-10.10.7.254) for our IPSEC Forticlient user and we did some change to a new scope (10.10.24.0-10.10.28.0).

 

But in the old IP Addresses remains in the routing monitor list as static addresses and in conflict with some we now need.

 

How can I do a purge or clean the routing-table ?

 

Regards

Okay I don't think that is your issue but to answer your question

 

1: to clear routes static you can do from the cli

 

e.g

 

  diag  ip route delete <intf> <route>

 

2: if you have a router process ( bgp ospf ) 

 

e.g

 

  execute router clear bgp <insert ? to see option>

 

 

3: in your issues, you need to search for the old range and ensure it's not being used

 

e.g

 

  show full | grep -f x.x.x.x

Thanks for your help.

 

I try and follow the ? help to set the command line for Interface and route

diag  ip route delete <intf> <route>

Command fail. Return code -1

Not possible to delete one route and i've more than 500 to delete (Ipadr Scope).

Does a Fortigate restart will solve the issue ?

yes obviously a restart will clear teh rib but what is your exact issue? It does not sound like a rib issue. What does

 

 

"get router info routing all " show you ?

 

Also , does it match "diag ip route list" ?

Yes it's the same list.

 

What do you mean by RIB ?

 routing information base (RIB)  == route-table

 

The RIB holds active and update routes.
