When configuring static neighbors on the Hub for ospf, I got the following error:

`%OSPF-4-CFG_NBR_INVAL_NET_TYPE: Can not use configured neighbor: neighbor command is allowed only on NBMA and point-to-multipoint networks`

I tried to remove the ip ospf network broadcast commands but it didn’t work.

Please assist.

I fixed the error. I changed Hub and Spokes’ Tunnel 0 to ip ospf network non-broadcast.
