[ filter-policy { acl6-number | ipv6-prefix
ipv6-prefix-name | route-policy

Optional.
Not enabled by default.
11. Specify the maximum
number of equal-cost load
balanced routes.
ipv6 maximum load-balancing number
Optional.
The default maximum
number of equal-cost
load balanced routes is
8.
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 for advertisement.
Configuring BFD for IPv6 IS-IS
Bidirectional forwarding detection (BFD) can quickly detect faults between IPv6 IS-IS neighbors 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:

8. Enable BFD for IPv6 IS-IS.
isis ipv6 bfd enable Not enabled by default.
Configuring IPv6 IS-IS MTR
On a network comprising both IPv4 and IPv6 topologies, the IPv4 and IPv6 topologies must be consistent
so that both IPv6 IS-IS and IPv4 IS-IS can use the SPF algorithm to perform route calculation. If they are
