of the command based on an access list. Notice the command show ip route list 1 in Example
6-20. Access list 1 is configured so that any route about network 10.0.0.0 is matched (permitted
by the access list) and all others are denied. By referring to the access list, the show ip route
output will be filtered, showing only a portion of the routes. This is particularly useful when
there are many routes in the routing table.
troubleshooting in larger networks.
but to also know two other NetWare protocols used by the router: Service Advertisement
Protocol (SAP) and Get Nearest Server (GNS). Because IPX RIP and IP RIP were originally
based on the same protocol (XNS RIP), the two are very similar. SAP and GNS have no
equivalent feature in TCP/IP. RIP for IPX works in a similar manner to IP RIP. The most
obvious difference is that IPX RIP advertises IPX network numbers, not IP subnet numbers.
Table 6-17 lists the similarities and differences.
counter of the number of ticks delay for this route. By default, a Cisco router treats a link as
having a certain number of ticks delay. LAN interfaces default to one tick and WAN interfaces
default to six ticks. The number of hops is considered only when the number of ticks is a tie.
By using ticks as the primary metric, better routes can be chosen instead of just using hop count.
For example, a three-hop, three-tick route that uses three Ethernets will be chosen over a two-
hop, eight-tick route that uses two Ethernets and a serial link.
