Hi,
I am trying to run RIPv2 in VRF and this doesn't seem to work correctly.
There is no RIP neighbor shown in BIRD, however a tcpdump running on the
interface is showing RIP packets IN/OUT, advertising and receiving routes.
The configuration is below, am I missing something?
ipv4 table xxx;
protocol direct direct_xxx {
vrf "xxx";
ipv4 {
table xxx;
import all;
};
interface "ens34";
}
protocol rip rip_xxx {
vrf "xxx";
ipv4 {
import all;
export all;
table xxx;
};
interface "ens34" {
metric 2;
version 2;
address 224.0.0.9;
mode multicast;
};
}
bird> show rip neighbors
rip_xxx:

bird> sh route table xxx
