Rick,
Yes, I'm sure. But, I discovered that shutting the frame relay interface on
a given router doesn't matter if other frame relay interfaces on other
routers are enabled.
I'm fairly sure this is why.
Let's say there are 4 routers (a thorugh d) running frame relay over a f/r
cloud. If any of the routers a - c have their f/r interfaces enabled and
the "no fram inverse-arp" hasn't been configured yet, they will reply to
inverse-arp requests sent by rtr d once it's f/r interface is enabled. So,
even though rtr d's f/r interface is shut and the "no fram inverse-arp"
command is configured, rtr d will still send out arp requests ( it just
respond to arp requests) as soon as it's f/r interface is enabled.
At least, that's my current impression. Hopefully, someone will correct me
if I'm wrong in any respect.
Thanks, Tim
