How do I add a MAC address to the arp table on a 7206 router?
Thank you.

You can use the global arp command to add a permanent ARP cache entry. For an ethernet example:
ARP 192.168.10.1 0000.0c79.c104 ARPA
reference

arp 1.2.3.4 44.44.44 arpa F0/0
will add an arp entry for 1.2.3.4.
If you are trying this because you are ARPing for things and not getting a response (you have something like
Protocol Address Age (min) Hardware Addr Type Interface
Internet 1.2.3.4 - Incomplete ARPA FastEthernet2/0.35) then statically entering ARPs isn't liekly to help you very much. ARP is a very reliable protocol, and if it isn't working then it is most likely symptomatic of a larger problem. Also, keeping all of your ARP's correct manually is a hellish job. If you are doing this as a security improvment (or because you have some brain-dead equipment that doesn't support ARP) then good luck
