Hello,

Could you please help with an OSPF configuration.

I have configured a GRE tunnel between two peers - '172.16.0.9' and '172.16.0.4'. I configured then a local address on the newly created tunnel interface '172.16.1.1'. I would like to configure bird to speak on the GRE interface.

I tried with the following configuration but I cannot see that bird is announcing anything:

# ifconfig

bird config:

protocol kernel {
  #  persist;             # Don't remove routes on BIRD shutdown
  scan time 20;       # Scan kernel routing table every 20 seconds
  export all;             # Default is export none
  learn;
  device routes;
}

protocol device {
  scan time 10;           # Scan interfaces every 10 seconds
}

#protocol direct {
#  interface "*";
#  export all;
#}

protocol ospf OSPF {
  rfc1583compat;
  export all;
  import all;

  area 172.16.0.0 {
    networks {
      172.16.1.0/24;
    };
}

Thanks in advance!
