Group Mode FR on ARN

[majestik]

I upgraded a hub-spoke, big end - little end, Group Mode Frame Relay network from BayRS 14.0 to 15.2 including Prom revisions.

Hub to spoke communication worked fine as before, however spoke to spoke comms was completely out of action. I tried adjacent hosts, static-arp entries and static-routes but no success.

In the end I had to change from group-mode to direct-mode and it worked straight away.

Does anyone know if this is a problem with 15.20 or if I left something out of the config?

Regards,

Jeter,

The problem with Group Mode is to do with ARP failures, which is why adjacent-hosts, which are essentially static-arp entries, should work. They didn't. Neither did static-routes, not that I expected them to!
