Configuring Bfd For Ipv6 Is-Is; Configuring Ipv6 Is-Is Mtr - HPE 5800 Series Configuration Manual

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:
Step
Enter system view.
1.
Enable an IS-IS process and

enter IS-IS view.
Configure the NET for the

Return to system view.
5.
Enter interface view.

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 different, routers supporting both IPv4 and IPv6 send IPv6 packets to routers
that do not support IPv6, and thus packet loss occurs.
To resolve this issue, you can configure IPv6 IS-IS Multi-Topology Routing (MTR) to perform route
calculation separately in IPv4 and IPv6 topologies.
