Hi all. I have Bird 2.0.8 on one of border routers, it runs with kernel 5.10.26 and uClibc-ng 1.0.38. It acts as RR and receives FV from uplink + FV from second border (also RR), and it has 2 routing tables (one which receives BGP routes, then routes sinks to main table. When second

Cs. We have full table on v4 and v6, and about 20 neighbors on each. Our route/max_size for v4 and and v6 are defaults (2M and 4096 respectively) - and as noted, these values are the same in our Stretch and Buster boxes. Andrew

We believe we are seeing this problem too, since a Stretch->Buster upgrade - was there a solution to this? Thanks Andrew.

Two similar kernel routes with different metrics on bird 1.6.4

Hi all. I have two default kernel routes with different metrics (for failover, when first gateway becomes unreachable - all traffic is switched to second gw). I want to pipe it to other kernel table to gracefully handle connections to second IP. Unfortunatelly, I can't force bird to learn

Hi. Try to assemble uClibc and bird with debug symbols, and try to analyze core dump. Also it'll be good to run bird (better- to use debug version) in valgrind - it'll show all suspicious cases (like access across array borders, use of uninitialized variables and so on). On 24.10.2018

Maybe you forgot to disable rp_filter on uplink ifaces? And prepend works for incoming traffic, for outgoing - there is localpref. So, if outgoing traffic goes via ISP2 and incoming passed via ISP1 - it's dropped if rp_filter is enabled. On 25.04.2017 10:36, Wojciech Bajorek wrote: Hi, I
