Policy-based redirection redundancy requires the determination of the reachability or unreachability of the active next hop and the other configured next hops. This feature can use ARP, NDP or Ping checking to make the determination.
Note
IPv6 Policy-Based Routing is not supported for traffic with Hop-by-Hop extension headers. Traffic will continue to be hardware forwarded, and will not be processed in slow path.To configure health checking for a specific flow-redirect-name, use the following command:
configure flow-redirect flow_redirect_name health-check [ping | arp | neighbor-discovery]To configure the ping interval and miss count for a next-hop, use the following command:
configure flow-redirect flow_redirect_name nexthop ip_address ping health-check interval seconds miss number
