4.3 Configuring IPv6 IS-IS Routing Information Control
4.3.1 Configuration Prerequisites
You need to complete the IPv6 IS-IS basic function configuration before configuring this
task.
4.3.2 Configuration Procedure
Follow these steps to configure IPv6 IS-IS routing information control:

Enter IS-IS view isis [ process-id ] ––
Define the priority for
IPv6 IS-IS routes
ipv6 preference { route-policy
route-policy-name | preference } *
Optional
15 by default
Configure an IPv6
IS-IS summary route
ipv6 summary ipv6-prefix
prefix-length [ avoid-feedback |
generate_null0_route | [ level-1 |
level-1-2 | level-2 ] | tag tag ] *
Optional
Not configured by
default
Generate an IPv6
IS-IS default route
ipv6 default-route-advertise
[ [ level-1 | level-2 | level-1-2 ] |
route-policy route-policy-name ]*
Optional
No IPv6 default
route is defined by
default.
Configure IPv6 IS-IS
to filter incoming
routes
ipv6 filter-policy { acl6-number |
ipv6-prefix ipv6-prefix-name |
route-policy route-policy-name }
import
Optional
No filtering policy is
defined by default
Configure IPv6 IS-IS
to redistribute routes
from another routing
protocol
ipv6 import-route protocol
[ process-id ] [ allow-ibgp ] [ cost
cost-value | [ level-1 | level-2 |
level-1-2 ] | route-policy
route-policy-name | tag tag-value ] *
Optional
Not configured by
default
Configure the filtering
of outgoing
redistributed routes
ipv6 filter-policy { acl6-number |
ipv6-prefix ipv6-prefix-name |
route-policy route-policy-name }
export [ protocol [ process-id ] ]
Optional
Not configured by
default
Enable route leaking
ipv6 import-route isisv6 level-2
into level-1 [ filter-policy
{ acl6-number | ipv6-prefix
ipv6-prefix-name | route-policy
route-policy-name } | tag tag ]*
Optional
Not enabled by
default
Specify the maximum
number of equal-cost
load balanced routes
ipv6 maximum load-balancing
number
Optional
4 by default
