Hi Bird users,

 

I need your kind assistance. We are running bird router in container and peering with one of the edge routers using iBGP. This for a looking glass.

 

All the routes are becoming unreachable due to next hops since the bird router is not feed with all the next hops in the network. How can get the issue resolved ? I want to the change the next hop on the bird router(I don’t want the peering router to be next-hop-self.). Sofar, I am unsuccessful.  By hashing out disable under the protocol, we see the interfaces in the routing table.

 

I have done so far following things and unsuccessful.

 

protocol direct {

#             disabled;                             # Disable by default

               ipv4;                                    # Connect to default IPv4 table

               ipv6;                                    # ... and to default IPv6 table

}

 

filter looking_glass

if ( net ~ [ 0.0.0.0/0{0,32} ] ) then

            {

                bgp_next_hop = 10.252.40.X; (tried both VM or gateway address for VM. Not successful sofar)

                accept;

            }

 

 

Please kindly advise for a working solution.
