AT-S63 Management Software Command Line Interface User’s Guide
Section VII: Internet Protocol Routing 555
Version 2 supports the addition of a password of up to sixteen
alphanumeric characters to protect routers and their tables from
incorporating bogus routing updates. The switch adds the password into
the routing table when it broadcasts the contents of the table to its
neighboring routing devices, which check the password prior to updating
their tables.
Note
A RIP version 2 password is sent in plaintext. The AT-S63
management software does not support encrypted RIP passwords.
The switch broadcasts its routing table every thirty seconds from those
interfaces that have RIP. This interval is not adjustable on the switch. The
entire table is sent with the following exceptions:
ˆ Dynamic RIP routes that fall under the split horizon rule.
ˆ Inactive interface routes where there are no active ports in the VLAN.
Note
The AT-S63 management software does not support the RIP
holddown and flush timers.
The commands for managing RIP are “ADD IP RIP” on page 575,
“DELETE IP RIP” on page 583, and “SET IP RIP” on page 593.
Note
RIP must be configured from the command line interface. RIP is not
supported in the menus and web browser interfaces.
Default Routes
A default route is used when the switch cannot find a route in its routing
table for a packet that needs to be forwarded to a remote destination.
Rather than discard the packet, the switch sends it to the next hop
specified in the default route.
A default route has an destination IP address of 0.0.0.0 and no subnet
mask. A default route can be enter manually in the form of a static route or
learned dynamically through RIP. A switch can have multiple default
routes.
