This attribute indicates which protocol is to run on a protocol port.
In the case of a lan media it is to be set to broadcast.
In the case of WAN media the following choices are to be exercised:
For running Pre-IPXWAN RIP set value to other.
For running numbered RIP set value to wanRip.
For running un-numbered RIP set value to unnumberedRip.
Setting this value to ppp will signify unnumbered Rip running on a ppp
port.
