Howdy Folks,
I m trying to make OSPF work between a Zebra FreeBSD router and an M10 Juniper, without success.
The drama takes place on a LAN, where I have a Cisco 7200 besides the Zebra and the Cisco.
Everything seems fine between the Cisco and the Juniper on the one hand, and between the Cisco and the Zebra on the other hand.
However, the Zebra and Juniper routers are stuck in the "ExStart" phase.
Has anyone managed to make Juniper/Zebra interoperate? Do you have any idea what could be wrong ?
The best I could find that is looking similar to my problem is: http://www.cisco.com/warp/public/104/12.html
but the Juniper and the Zebra both report a 1500 bytes MTU on the interface, so it must be something else.
Cheers,
Tom (and Arnaud)
