Configuration Guide - IP Unicast Routing

S7700 and S9700 V200R011C10

This document describes IP Unicast Routing configurations supported by the switch, including the principle and configuration procedures of IP Routing Overview, Static Route, RIP, RIPng, OSPF, OSPFv3, IS-IS(IPv4), IS-IS(IPv6), BGP, Routing Policy ,and PBR, and provides configuration examples.

Configuring Convergence Priorities for IS-IS Routes

Configuring Convergence Priorities for IS-IS Routes

Context

You can configure the highest convergence priority for specific IS-IS routes so that these IS-IS routes will be converged first when a network topology changes.

The application rules of the convergence priorities for IS-IS routes are as follows:
  • Existing IS-IS routes are converged based on the priorities configured in the ipv6 prefix-priority command.

  • New IS-IS routes are converged based on the priorities configured in the ipv6 prefix-priority command.

  • If an IS-IS route conforms to the matching rules of multiple convergence priorities, the highest convergence priority is used.

  • The convergence priority of a Level-1 IS-IS route is higher than that of a Level-2 IS-IS route.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run isis [ process-id ]

    The IS-IS view is displayed.

  3. Run ipv6 prefix-priority [ level-1 | level-2 ] { critical | high | medium } { ipv6-prefix prefix-name | tag tag-value }

    Convergence priorities are set for IS-IS routes.

    By default, the convergence priority of 32-bit host routes is medium, and the convergence priority of the other IS-IS routes is low.

    NOTE:

    The ipv6 prefix-priority command is only applicable to the public network.

    After the ipv6 prefix-priority command is run, the convergence priority of 32-bit host routes is low, and the convergence priorities of the other routes are determined as specified in the ipv6 prefix-priority command.

  4. (Optional) Run quit

    The system view is displayed.

  5. (Optional) Run ipv6 route prefix-priority-scheduler critical-weight high-weight medium-weight low-weight

    The preference-based scheduling ratio of IPv6 routes is configured.

    By default, the preference-based scheduling ratio of IPv6 routes is 8:4:2:1.
