I have not configured IP SLA object tracking on nexus OS before and its looks a bit confusing. Can someone help me interpret the following configuration?
This example shows that object tracking is configured for PBR: ! Configure and schedule IP SLA operations ip sla 1 icmp-echo 10.3.3.2 ip sla schedule 1 life forever start-time now ! ip sla 2 udp-echo 10.4.4.2 ip sla schedule 2 life forever start-time now ! ip sla 3 icmp-echo 10.5.5.2 ip sla schedule 3 life forever start-time now ! ip sla 4 icmp-echo 10.6.6.2 ip sla schedule 4 life forever start-time now ! ip sla 5 icmp-echo 10.7.7.2 ip sla schedule 5 life forever start-time now ! ! Configure Object Tracking to track the operations ! track 1 ip sla 1 reachability track 2 ip sla 2 reachability track 3 ip sla 3 reachability track 4 ip sla 4 reachability track 5 ip sla 5 reachability ! ! Configure ACL ip access-list standard ACL permit ip 10.2.2.0/24 10.1.1.1/32 ! ! Configure PBR policing on the router route-map PBR match ip address ACL set ip next-hop verify-availability 10.3.3.2 track 1 set ip next-hop verify-availability 10.4.4.2 track 2 set ip next-hop verify-availability 10.5.5.2 track 3 ! ! Apply PBR policy on the incoming interface of the router. interface ethernet 0/0 ip address 10.2.2.1 255.255.255.0 ip policy route-map PBR
Lets focus on object tracking 1 -- Does it mean as long as TRACK 1 is valid, verify and use 10.3.3.2 as the next hop for the ACL for the routing (ignoring whatever is in the current route table)?
