[OLSR-users] OLSR and Zebra

[Russell Handorf]

Thanks for the input,

Do you know of any other OSPF routing protocol that will allow OLSR and OSPF
to play nicely? (Other than Zebra) Do you have a link for this demo code?

Thanks,

r

That's because there is no quick fix.

I thought it to be that simple as well; it is not see below:

This does not work because zebra marks the OLSR kernel routes as
inactive.  Quick fix is to hack the zebra daemon; real fix is to
implement a zebra client in OLSRd to talk to zebra.  You want to take
the HNA4 set from OLSRd (implement a module) and send them to zebra
(using the Z-protocol).

I have some example code for this; but nothing mature enough to be
deployed in any live network.

This is a real stumble block for OLSRD deployment IMHO; anyone whishing
to deploy this (with dynamic redistribution) in a network where OSPF is
the IGP is out of luck currently...
