Hi all,


I'm new to Draytek as a product and have just purchased a Vigor 3900.

I am trying to set up OSFP between the Vigor and a Digi Wr44 router, which are running over IPsec & GRE.



I have checked the following things so far trying to form neighbours:
IPsec has multicast VPN enabled on Vigor 3900
Hello and dead timers are the same on both ends.
local LANs at both sides and gre interfaces have the same mask
both routers are in the same area
both routers are advertising the local lan interfaces and the GRE tunnel interfaces.

I have used wireshark on both lans and can see the hello packets being sent from the local lan interfaces and the GRE tunnel interfaces at the vigor3900 end trace but no hello packets seen at the third party router from the Vigor 3900.

When i look at the Vigor 3900 routing table, the route for the GRE tunnel network is via the default gateway but i expect it to appear directly connected as a gre tunnel endpoint.
Does anyone know how to perform any osfp debugging on the Vigor 3900 as I cannot get neighbours to form.
Thanks in advance.
Adrian
