Configuring the Update Interval of IPX RIP The switch broadcasts RIP update
packets periodically. You can configure the update interval of IPX RIP with the
following command.
Perform the following configuration in system view.
Configuring the Update Interval of IPX RIP
Table 22
Operation
Configure the update interval of IPX RIP
Restore the default update interval of IPX RIP
By default, IPX RIP sends routing updates every 60 seconds.
For the synchronization of routing tables, all the switches on the network must
have the same RIP update interval.
Configuring the Aging Period of IPX RIP The aging period of IPX RIP is a
multiple of the IPX RIP update interval. With the following command, you can set
the multiplier.
Perform the following configuration in system view.
Table 23 Configuring the Aging Period of IPX RIP
Operation
Configure the aging period of IPX RIP
Restore the default aging period of IPX RIP
By default, the aging period is three times the RIP updating interval. If a routing
entry is not updated after three RIP update intervals, it is deleted from the routing
table. At the same time, its associated dynamic service entry is deleted from the
server information table.
Configuring the Size of IPX RIP Update Packets Perform the following
configuration in VLAN interface view.
Table 24 Configuring the Size of IPX RIP Update Packets
Operation
Configure the size of IPX RIP update packets
Restore the default packet size
By default, the maximum IPX RIP update packet size is 432 bytes. Considering the
32 bytes for the IPX and RIP headers, each update packet can carry up to 50
eight-byte routing entries.
Configuring the IPX Packet Forwarding Delay on a VLAN Interface IPX RIP
uses hop count and ticks to measure the distance to a destination network and
route packets. The hop count of a packet adds by one upon each forwarding.
Ticks (1 tick = 1/18 seconds) indicate the delay that a VLAN interface experiences
to forward an IPX packet: a longer delay means slower forwarding whereas a
shorter delay means faster forwarding.
