Hi List,
we setup a hub&spoke vpn based on junipers route based VPN with OSPF P2MP
interfaces on the hub. We created two OSPF stub areas - there contains
about ~27 OSPF neigbors each. All spokes (ns5gt+, 5.3.0r2) are connected
with ADSL 2000 and ADSL 1000 and the dual hubs (ns50adv, 5.3.0r4) with
SDSL.
Sometimes the neighbors stuck in OSPF exstart/exchange state and we cant
identify why. We did a debug ospf all on a spoke (192.168.10.x are the
tunnel interfaces) see above. Does anyone know why the spokes doesnt
recognize a DR/BDR? (dr 0.0.0.0 bdr 0.0.0.0) We configured the hubs with
a higher OSPF priority as the spokes where never elected as DR/BDR. Or
could mismatching MTU´s be the problem?
any hint? thx!
