3. Filter routes calculated
using received LSPs.
filter-policy { acl-number | prefix-list
prefix-list-name | route-policy
route-policy-name } import
By default, IS-IS route
filtering is not configured.
Filtering redistributed routes
IS-IS can redistribute routes from other routing protocols or other IS-IS processes, add them to the IS-IS
routing table, and advertise them in LSPs.
Perform this task to filter redistributed routes. Only routes that are not filtered can be added to the IS-IS
routing table and advertised to neighbors.
To filter redistributed routes:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter IS-IS IPv4 unicast address
family view or IS-IS IPv4 unicast
topology view.
• Enter IS-IS IPv4 unicast address family
view:
a. isis [ process-id ] [ vpn-instance
vpn-instance-name ]
b. cost-style { wide | wide-compatible }
c. address-family ipv4 [ unicast ]
• Enter IS-IS IPv4 unicast topology view:
d. isis [ process-id ] [ vpn-instance
vpn-instance-name ]
e. cost-style { wide | wide-compatible }
f. address-family ipv4 [ unicast ]
g. topology topo-name tid tid
Use either method.
3. Filter routes redistributed from
other routing protocols or IS-IS
processes.
filter-policy { acl-number | prefix-list
prefix-list-name | route-policy
route-policy-name } export [ protocol
[ process-id ] ]
By default, IS-IS route
filtering is not
configured.
Configuring IS-IS route leaking
Perform this task to control route advertisement (route leaking) between Level-1 and Level-2.
You can configure IS-IS to advertise routes from Level-2 to Level-1, and to not advertise routes from Level-1
to Level-2.
To configure IS-IS route leaking:
