Hello Constantin,

 

What is URPF?

who proposed it?

what is it for?

 

is there anything better than a network administrator who understands the network and how to solve the "BellmanFord problem" as seen by your network or do you want to outsource him too?

Dear Lars,

I addressed this message to the list so you can feel free to express yourself.

 

I try not to consider ip acl as an option, because it can become extremely difficult to manage it for a number of customers.

I am interested if anyone had to deal with this problem …

 

Tks,

Sorry Constantin,

 

We can't answer this because we're afraid of violating your Mobifon SA Romania Confidential and Proprietary Information notification...

Subject: [MPLS-OPS]: URPF for route-leaking / vpn-mpls

Hello,

 

How can I assure that my vpn-mpls clients cannot use rfc1918 sourced ip packets (or spoof ) in case they have also internet access configured by route-leaking ?

 

If I use URPF it will look in the vrf’s FIB (not in the global RoutingTable FIB ) so it will let pass ip packets sourced with private addresses.

 

Any nice implementation you can share w/ me ?

 

Tks,
