Displaying And Maintaining Ipv6 Urpf; Ipv6 Urpf Configuration Example - HP MSR Series Configuration Manual

•
Do not configure the allow-default-route keyword for loose IPv6 uRPF check. Otherwise, IPv6
uRPF might fail to work.
To enable IPv6 uRPF on an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Enable IPv6 uRPF on the
interface.

Displaying and maintaining IPv6 uRPF

Execute display commands in any view.
Task
Display IPv6 uRPF configuration (centralized
devices in standalone mode).
Display IPv6 uRPF configuration (distributed

devices in IRF mode).

IPv6 uRPF configuration example

Network requirements
As shown in
permit packets from network 1010::/64.
Configure strict IPv6 uRPF check on GigabitEthernet 2/0/1 of Router A and allow using the default
route for IPv6 uRPF check.
