Cisco Nexus - ITD Bucket Question

Does anyone know what the IP addresses are that are in the route map generated when ITD is configured on a Cisco Nexus?

 

Example:

 

ip access-list ITD1_itd_bucket_2

  10 permit ip 1.1.1.16 255.255.255.15 any

ip access-list ITD1_bucket_3

  10 permit ip 1.1.1.32 255.255.255.15 any

ip access-list ITD1_itd_bucket_4

  10 permit ip 1.1.1.48 255.255.255.15 any

ip access-list ITD1_itd_bucket_5

 

I'm guessing that these are the IP's addresses of the buckets themselves? None of the official documentation explains this unfortunately. Apologies if this a stupid question but I can't see these IP's addresses anywhere else in our configs or the routing table.

Hi @FC49 

As you correctly guessed, the automatically created ACL are used for route-map policies to perform PBR functionality to redirect and Load balance traffic. Basically these are the buckets to each node defined to be LB via a PBR.

To check the full config, including route maps and how these are used, use the following two commands:

show run | section itd
show itd

Stay safe,
