Enabling Ipv6 Is-Is Mtr - HP FlexFabric 12900E Series Configuration Manual

Step
1. Enter system view.
2. Enter interface view.
3. Enable BFD control packet
mode for IPv6 IS-IS FRR.
To enable BFD echo packet mode for IPv6 IS-IS FRR:
Step
1. Enter system view.
2. Configure the source IPv6
address of BFD echo packets.
3. Enter interface view.
4. Enable BFD echo packet
mode for IPv6 IS-IS FRR.

Enabling IPv6 IS-IS MTR

On a network, 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 might send IPv6 packets to routers that do not support IPv6, resulting in packet loss.
To resolve this issue, configure IPv6 IS-IS Multi-Topology Routing (MTR) to perform route calculation
separately in IPv4 and IPv6 topologies.
