By default, the update interval of
IPX RIP is 60 seconds.

By default, the aging interval is
three times the RIP updating

ipx network network
Required
By default, the system does not
assign network numbers to VLAN
interfaces. That is, IPX is disabled
on all VLAN interfaces.
Configure the size of
IPX RIP update
packets
ipx rip mtu bytes
Optional
By default, the maximum size of
IPX RIP update packets is 432
bytes.
Configure the IPX
packet forwarding
delay on a VLAN
interface
ipx tick ticks
Optional
By default, the forwarding delay
on the VLAN interface is one tick.
After IPX RIP is enabled, the switch broadcasts IPX RIP update packets periodically.
You can configure the update interval of IPX RIP as required. Note that for the
synchronization of routing tables, all the switches on the network must have the same
RIP update interval.
The aging interval of IPX RIP is a multiple of the IPX RIP update interval. You can set
multiple update intervals as an aging interval. If a routing entry is not updated at the
expiry of one RIP aging interval, it will be deleted from the routing table. At the same
time, its associated dynamic service entry will be deleted from the service information
table.
By default, the maximum IPX RIP update packet size is 432 bytes. Considering the 32
bytes for the total length of IPX and RIP headers, each update packet can carry up to
50 eight-byte routing entries by default.
IPX RIP uses “hops” and “ticks” to measure the distance to a destination network and
route packets. The hop count is incremented by 1 every time the packet is forwarded.
Ticks (1 tick = 1/18 seconds) indicate the delay that a VLAN interface experiences to
