I'm having troubles with finding the neighbors after the IPIP tunnels
configurations where I have 4 VPCs and deployed there 4 CSR routers (for more details about the configuration, I posted yesterday in Network Engineering section OSPF over IPIP tunnel doesn't work for CSR 1000v in AWS). I configured OSPF
in the tunnels. Below is the configuration for one router.
Routing Protocol is "ospf 1"
Router ID 172.3.1.38
Number of areas in this router is 1. 1 normal 0 stub 0 nssa
Maximum path: 4
Routing for Networks:
10.10.3.0 0.0.0.3 area 0
10.10.4.0 0.0.0.3 area 0
The interfaces are configured and as well as the tunnels which are up
.
My problem is that I cannot see the neighbors using sh ip ospf neighbor
, it shows nothing.
Is it coming for that AWS
does not supports link-local multicast
where multicast is needed for protocols like OSPF
and EIGRP
for the discovery and hello mechanisms?
