mpc5121 linux boot via nfs not working

I'm new to LTIB.  I'm having trouble getting an nfs mount of my rootfs to work.   I followed the instructions in AN3765: Porting Linux for the MPC5121e, Appendix B.  Linux boot using "run net_nfs" fails with an "nfs: server not responding" error.  I then tried to simply mount the rootfs manually and that fails with a "Protocol not supported" error.  Both host and target have fixed IP addresses.  Specifics:





host>cd /tftpboot 

host>ls -l ltib
lrwxrwxrwx 1 brenda brenda 24 2009-04-20 14:16 ltib -> /home/brenda/ltib/rootfs




target>mount /mnt
mount: mounting on /mnt failed: Protocol not supported


The host syslog simply shows that mountd authenticated a mount request from  I've been trying to figure out what the "Protocol not supported" error means with no luck.  Any help appreciated.
