route-policy route-policy-name }

export [ protocol [ process-id ] ]

Optional.
Not configured by default.

10.

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.
Disabled by default.

11.

Specify the maximum

number of equal-cost load
balanced routes.

ipv6 maximum load-balancing

NOTE:

The ipv6 filter-policy export command is usually used in combination with the ipv6 import-route
command. If no protocol is specified for the ipv6 filter-policy export command, routes redistributed from

all routing protocols are filtered before advertisement. If a protocol is specified, only routes redistributed
from the routing protocol are filtered before advertisement.

Configuring BFD for IPv6 IS-IS

Bidirectional forwarding detection (BFD) provides a mechanism to quickly detect the connectivity of links

between IPv6 IS-IS neighbors, thus to improve the convergence speed of IPv6 IS-IS. For more information

about BFD, see High Availability Configuration Guide.
To configure BFD for IPv6 IS-IS:

Step Command
