Configuring ANCP Neighbors

date_range 06-Dec-23

You must configure each neighboring access node that you want the ANCP agent to monitor and potentially shape traffic for. Some neighbor settings override globally configured values.

To configure an ANCP neighbor:

  1. Specify the IP address of the neighbor.
    content_copy zoom_out_map
    [edit protocols ancp]
    user@host# set neighbor 203.0.113.234
    
  2. (Optional) Configure the neighbor to operate in a backward-compatible mode when it does not support the current IETF standard and the backward-compatible mode is not configured globally.
    content_copy zoom_out_map
    [edit protocols ancp neighbor 203.0.113.234]
    user@host# set pre-ietf-mode
    
  3. (Optional) Override the globally configured backward-compatible mode when the neighbor supports the current IETF standard.
    content_copy zoom_out_map
    [edit protocols ancp neighbor 203.0.113.234]
    user@host# set ietf-mode
    
  4. (Optional) Configure the interval in seconds between ANCP adjacency messages exchanged with this neighbor.
    content_copy zoom_out_map
    [edit protocols ancp neighbor 203.0.113.234]
    user@host# set adjacency-timer 20
    
  5. (Optional) Specify the maximum number of discovery table entries that are accepted from this neighbor.
    content_copy zoom_out_map
    [edit protocols ancp neighbor 203.0.113.234]
    user@host# set maximum-discovery-table-entries 10000
    
  6. (Optional) Enable out-of-band ANCP triggering of autosensed, dynamic VLANs on the physical interface.
    content_copy zoom_out_map
    [edit protocols ancp neighbor 203.0.113.234]
    user@host# set auto-configure-trigger interface ge-1/0/0
    
  7. (Optional) Configure how long the ANCP agent maintains a Layer 2 wholesale session when an adjacency loss occurs.
    content_copy zoom_out_map
    [edit protocols ancp neighbor 203.0.113.234]
    user@host# set adjacency-loss-hold-time 10
