ABLE
The switch builds and maintains an IPX routing table. As in the case of IP, the table is
populated using dynamic and static entries.
D
YNAMIC ROUTES
Dynamic routes are typically learned by way of IPX/RIP. Routers that use IPX/RIP
exchange information in their routing tables in the form of advertisements. Using
dynamic routes, the routing table contains only networks that are reachable.
Dynamic routes are aged out of the table when an update for the network is not
received for a period of time, as determined by the routing protocol.
S
TATIC ROUTES
Static routes are manually entered into the routing table. Static routes are used to reach
networks not advertised by routers. You can configure up to 64 static IPX routes on the
switch. Static routes are never aged out of the routing table. Static routes are advertised
to the network using IPX/RIP.
IPX/RIP R
OUTING
The switch supports the use of IPX/RIP for unicast routing. IPX/RIP is different from
IP/RIP. However, many of the concepts are the same. ExtremeWare supports the
following IPX/RIP features:
• Split horizon
• Poison reverse
• Triggered Updates
Route information is entered into the IPX route table in one of the following two ways:
• Dynamically, by way of RIP
• Statically, using the command:
config ipxroute add [<dest_netid> | default] next_hop_netid
next_hop_node_addr <hops> <ticks>
