This happens to me in frame-relay lab. Apparently the inverse arp does not
function the way it should in lab. Right now I always do 'copy run start',
then 'reload' on all lab routers to make sure that the inverse arp and
what-not work as it should.
In a recent actual frame relay implementation between two sites, we had to
config the lmi type at one site in order to bring up frame-relay connection.
We were using 1720 with v. 12.1(1) at both sites.
