How many PBR-based routes do Huawei switches support

Huawei switches support four PBR-based routes. That is, a maximum of four next hop addresses can be defined in a traffic behavior.

When the redirect ip-nexthop or redirect ipv6-nexthop command is used to configure multiple next hop IP addresses, the switch redirects packets in active/standby mode. The device determines the primary path and backup paths according to the sequence in which next hop IP addresses were configured. The next hop IP address that was configured first has the highest priority and this next hop is used as the primary path. Other next hops are used as backup paths. When the primary link becomes Down, a next hop with higher priority is used as the primary link.

When the redirect ip-multihop or redirect ipv6-multihop command is used to configure multiple next hop IP addresses, the switch redirects packets using equal-cost routes in load balancing mode. The switch selects a next hop IP address based on source IP addresses of the packets. That is, if the source IP addresses of the packets are the same, the switch forwards the packets to the same next hop regardless of the traffic volume.
