Section VII: Internet Protocol Routing 669
This command changes RIP on the VLAN11-0 interface to accept both
RIP version 1 and version 2 packets:
set ip rip interface=vlan11-0 receive=both
This command changes RIP on the VLAN22-1 interface to send and
receive RIP version 1 packets. Since version 1 does not support password
authentication, the command disables it:
set ip rip interface=vlan22-1 send=rip1 receive=rip1
authentication=none
Note
Password authentication must be disabled to change an interface
from RIP version 2 to version 1.
