Distribute Routes
Another method of controlling routing information is to filter the information through a prefix list. Prefix
lists are applied to incoming or outgoing routes and routes must meet the conditions of the prefix lists or
FTOS does not install the route in the routing table. The prefix lists are globally applied on all interfaces
running IS-IS.
Configure the prefix list in the PREFIX LIST mode prior to assigning it to the IS-IS process. For
configuration information on prefix lists, see
Route-maps.
IPv4 routes
Use the following commands in ROUTER ISIS mode to apply prefix lists to incoming or outgoing IPv4
routes.
Note: These commands apply to IPv4 IS-IS only. Use the ADDRESS-FAMILY IPV6 mode shown later to
apply prefix lists to IPv6 routes

Purpose
Apply a configured prefix list to all incoming
IPv4 IS-IS routes.
Enter the type of interface and slot/port
information:
• For a 1-Gigabit Ethernet interface, enter
the keyword GigabitEthernet followed
by the slot/port information.
• For the Loopback interface on the RPM,
enter the keyword loopback followed by
a number from 0 to 16383.
• For a port channel, enter the keyword
port-channel followed by a number from
1 to 255 for TeraScale and ExaScale, 1 to
32 for EtherScale.
• For a SONET interface, enter the keyword
sonet followed by slot/port information.
• For a 10-Gigabit Ethernet interface, enter
the keyword TenGigabitEthernet
followed by the slot/port information.
For a VLAN, enter the keyword vlan
•
followed by a number from 1 to 4094.
E-Series ExaScale platforms support
4094 VLANs with FTOS version
8.2.1.0 and later. Earlier ExaScale
supports 2094 VLANS.
