I have two ebgp peers connected to my quagga 1.0.20160315 router.
One of those peers (peer1) is advertising routes with flag 0x800 (Optional Non-Transitive) in the MP_REACH_NLRI path attribute. Also the next hop is marked as Optional Non-Transitive.
My quagga router is not advertising this route to the other peer2 and I suspect this is because of the Non-Transitive flags in the path attribute.
Is their a way to override non-transitive flag in incoming routes and redistribute them to all the other peers?
Thanks in advance for the help. Regards
Update I got it working by using a route map and re-writing the bgp next hop. Original route was not advertised because of Non Transitive flags.
