Kernel protocol and IPv6 route issue with Bird 2.0

2019-09-11 Thread Nigel Kukard
Hi guys, I'm having an issue where IPv6 routes from the kernel routing table don't appear to end up in my t_kernel6 table. Despite the next-hop being link-local and the interface being UP. IPv4 routes I have no problem with, working as expected. I must be doing something wrong on my side, if

Hi guys, Is there perhaps an equivalent in BIRD for the following... ^(65000_)+(65101_)+(65253_)+$ The closest I could come was the following, but I am unsure if it would match if any of the networks prepend. if (bgp_path ~ [= 65000 65101 65253 =]) -N

RTS_STATIC_DEVICE oddity

Hi guys, I may be going blind or just dumb, but I could of sworn this worked like a year ago in v2. I have a t_static4 table, with a static device route, I pipe this to my master4 table, then pipe my master4 table to RIP and only pick out the RTS_STATIC_DEVICE routes. However the source is set

OSPF protocol and export filters for E2 routes

2020-12-09 Thread Nigel Kukard
Hi guys, I'm wondering if someone knows the answer to this, here is the setup... R1 => R2 => R3 - R1 advertises a route (in this case 0.0.0.0/0)  to R2  (from static or kernel) - R2 accepts the route with "import all" - R2 has a filter for the route with "export my_filter;" and in that

Possibly a way to match Kernel.source field?

Hi there fellow BIRD users, Does anyone perhaps know if there is a way to match this field? I'm trying to create a filter to prevent these from being imported into my one table which I feed into OSPF6. I've tried, Kernel.source and kernel.source sadly with no luck. This item corresponds to
