HP MSR SERIES Command Reference

543
For asymmetrical routing where the interface receiving upstream traffic is different from the interface
forwarding downstream traffic on a PE device, configure loose IPv6 uRPF to avoid discarding valid
packets. If the two interfaces are the same (symmetrical routing), configure strict IPv6 uRPF. An ISP usually
adopts symmetrical routing on a PE device.
You can use an ACL to match specific packets, so they are forwarded even if they fail to pass IPv6 uRPF
check.
Examples
# Configure strict IPv6 uRPF check on interface GigabitEthernet 2/1/2, which allows using the default
route and uses IPv6 ACL 2999 to match packets.
<Sysname>system-view
[Sysname]interface gigabitethernet 2/1/2
[Sysname-GigabitEthernet2/1/2]ipv6 urpf strict allow-default-route acl 2999
# Configure loose IPv6 uRPF check on interface GigabitEthernet 2/1/1.
<Sysname>system-view
[Sysname]interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1]ipv6 urpf loose
