Hi Everyone
I'm not sure if this is a proper group for asking about an issue I have.
I'm new to BIRD and decided to build POC where I have a bunch of servers
(SRV1, SRV2, SRVxx) with BIRD and the same /32 prefixes on loopback
interfaces. Those prefixes are sent to RT-MAIN. To have only one active
server with designated IP prefix I decided to prepend the prefix on
other servers n times. This configuration works fine. Failovers work
perfectly but with infrastructure I have with a lot of changes I have to
use an agent to refresh BIRD configuration files very often. To get rid
of this problem I came with an idea to use a management routers
connected to all servers sending the same prefixes as on my servers but
with communities, e.g. (65000,n) where n means how many times prefix
should be prepended on server. Topology would look like this:
NET
|
|
RT-MAIN --- SRV2
| |
||
SRV1 --- RT-MGMT
This is an idea but I have a problem with implementation. Is it possible
with BIRD to write an export filter which will be able to use
communities received prom other peer? For example, if SRV1 receives
prefix 10.1.1.1/32 with community (65000,3) form RT-MGMT and this prefix
is configured on interface lo then it should be send to RT-MAIN
prepended three times
