As shown in
support both IPv4 and IPv6. Router C supports only IPv4 and cannot forward IPv6 packets.
Enable IPv6 IS-IS MTR on Router A, Router B, Router C, and Router D to make them perform route
calculation separately in IPv4 and IPv6 topologies. With this configuration, Router A does not forward
IPv6 packets destined to Router D through Router B, avoiding packet loss.
Configuration prerequisites
Before you configure IPv6 IS-IS MTR, configure basic IPv4 and IPv6 IS-IS functions, and establish
IS-IS neighbors.
Configuration procedure
To enable IPv6 IS-IS MTR:
Step
1. Enter system view.
2. Enter IS-IS view.
3. Specify an IS-IS cost style.
4. Enter IPv6 address family
view.
5. Enable IPv6 IS-IS MTR.
