Configuration Prerequisites; Configuration Procedure; Displaying And Maintaining Ipv6 Is-Is - HP MSR2000 series Configuration Manual

Figure 112 Network diagram
In Figure 1 12, the numbers refer to the link costs. Router A, Router B, and Router D 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. In this way, Router A will not forward IPv6 packets
destined to Router D through Router B to avoid packet loss.

Configuration prerequisites

Before configuring IPv6 IS-IS MTR, you must configure basic IS-IS functions, and establish IS-IS neighbors.

Configuration procedure

To configure IPv6 IS-IS MTR:
Step
1. Enter system view.
2. Enter IS-IS view.
3. Specify the cost style for IS-IS.
Enable IPv6 IS-IS MTR.
4.
