vyos@vyos# show interfaces tunnel
tunnel tun0 {
address 10.10.10.2/30
encapsulation gre
ip {
ospf {
network point-to-point
}
}
local-ip 38.140.xx.xx
remote-ip 200.125.xx.xx
source-interface eth0
}
[edit]

this is my GRE Tunnel Link

and then my ospf

vyos@vyos# show protocols
bgp 30542 {
neighbor 38.140.xx.xx {
address-family {
ipv4-unicast {
route-map {
export ISP-COGENTv4-OUT
import ISP-COGENTv4-IN
}
}
}
remote-as 174
}
}
ospf {
area 0 {
network 10.10.10.0/30
}
log-adjacency-changes {
}
parameters {
router-id 10.10.10.2
}
}
static {
route 0.0.0.0/0 {
next-hop 38.140.xx.xx {

Thanks, that work perfeclty for me, i do this including your command.

set interfaces tunnel tun0 ip ospf dead-interval 6
set interfaces tunnel tun0 ip ospf hello-interval 2
set interfaces tunnel tun0 ip ospf priority ‘1’
set interfaces tunnel tun0 ip ospf retransmit-interval ‘5’
set interfaces tunnel tun0 ip ospf transmit-delay ‘1’
set interfaces tunnel tun0 parameters ip ttl 200

So now i can step forward with my test

Thanks.
